Answer:
x=29
Step-by-step explanation:
The sum of angles in a triangle is 180deg.
We know this is a right triangle, so the third angle is 90deg, leaving us with 90deg for the other two.
(2x-2) + (x+5) = 90
3x + 3 = 90
3x = 87
x = 29

The parallelogram whose diagonals are equal in length and not perpendicular is
called
(a) square
(b) rectangle.
(d) straight.
(c) rhombus.
(d) trapezium
Answers
Answer:
Rectangle.
Step-by-step explanation:
If the diagonals are equal then the parallelogram is a rectangle. They are also equal in length in a square, which can be regarded as a special type of rectangle - but in this case the diagonals are perpendicular. They are also perpendicular in a rhombus.

Answers
Answer:
x= 79 y= 15 m=54
Step-by-step explanation:
both triangles are basically mirrored, so since x+11 is in the same position as angle H the real equation would be: x+11=90 and the same thing for y+7 because that side is the same as side FG the equation would be y+7=22. For M since angles E and H are 35 and 90 you just add them together and then subtract them from 180 because are triangles add up to 180 degrees in terms of angles not sides.
Answer:
y = 15
x = 1.93 wrong x = 79
m∠GFH = 54°
Step-by-step explanation:
y + 7 = 22
y = 15
sin 36° = (x + 11)/22
0.5878 = (x + 11)/22
x + 11 = 12.93
x = 1.93
m∠GFH = 90° - 36° = 54°
hi pls help me in math im soo stuck:(((plss
Answers
Answer/Step-by-step explanation:
a. First, find the value of a.
Sum of the interior angles of a triangle = 180° (triangle sum theorem)
Therefore:
3a + 2a + a = 180°
Add like terms
6a = 180°
6a/6 = 180/6
a = 30
Thus:
a = 30°
2a = 2(30) = 60°
3a = 3(30) = 90°
b. The triangle is an isosceles triangle because it has two sides that are indicated to be equal. This also implies that the angels opposite each of the equal sides are also congruent to each other.
Therefore, sum of the isosceles triangle would be:
2(2x) + 5x = 180°
4x + 5x = 180
9x = 180
9x/9 = 180/9
x = 20
Thus:
2x = 2(20) = 40
5x = 5(20) = 100

A researcher in sports equipment is investigating the design of racing swimsuits for women. The researcher selected a sample of 40 women swimmers from high school swim teams in the state and randomly assigned each swimmer to one of two groups: suit A or suit B. The women will wear the assigned suits for a certain race, and the mean swim times for each group will be recorded. The difference in the sample mean swim times will be calculated. Which of the following is the appropriate inference procedure for analyzing the results?
A. A two-sample t-interval for a difference between sample means
B. A two-sample t-interval for a difference between population means
C. A one-sample t-interval for a sample mean
D. A one-sample t-interval for a population mean
E. A matched pairs t-interval for a mean difference
Answers
Answer:
B. A two-sample t-interval for a difference between population means
Step-by-step explanation:
in the given situation we are comparing the groups that are independent also we test the difference of the population mean so here consider inference procedure for analyzing the results is that there should be two sample t -interval by taking a difference between the population means
hence, the correct option is B.

Answer:
In some cases with exponential functions, as the value of x increases, the value of y also increases. This is a direct relationship known as exponential growth. As the value of x increases, the value of y grows rapidly. ... This is an inverse relationship known as decay.
