<u><em>Explanation:</em></u>
<u>An isometry is</u> a transformation that preserves the size of the pre-image in the image and the corresponding angles and sides are also congruent.
<u>In each one of the images</u>, the figure given is he same size as the pre-image and The corresponding angles and corresponding sides are congruent; therefore they are all isometries. </span></span>
Solution:
The interior angles of a triangle sum up to 180°
<u>This means that...</u>
<u>Simplify the distributive property.</u>
<u>Combine like terms.</u>
- 3x + (6 + 52 + 35) = 180
- => 3x + (93) = 180
<u>Subtract 93 both sides.</u>
- 3x + (93) = 180
- => 3x + 93 - 93 = 180 - 93
<u>Simplify both sides.</u>
<u>Divide 3 both sides.</u>
- => 3x/3 = 87/3
- => x = 87/3 = 29
The population standard deviation, σ = 1.68, the sample standard deviation, s = 1.95, the sample mean =7.23, and the sample size, n = 39.The test statistics is given by
T=(n - 1) (s / σ)²
= (39 - 1) (1.95 / 1.68)²
= 38 (1.35)= 51.196
Answer:
They are complementary.
Step-by-step explanation:
we know that
The sum of the interior angles of a triangle must be equal to 180 degrees
so
A+B+C=180°
where
A,B and C are the measures of the interior angles of triangle
In a right triangle
The measure of angle C ( I assume that the right angle is C) is equal to 90 degrees
so
A+B+90°=180°
A+B=180°-90°
A+B=90°
Remember that
If two angles are complementary, then their sum is equal to 90 degrees
therefore
A and B are complementary angles
