The measure of one interior angle of a triangle is 45°. what can you conclude about the other two interior angles of the triangle?

a. one of the other angles must be a right angle.
b. the sum of the measures of the other two angles is 135°.
c. the other two angles must be acute angles.
d. one of the other angles must have a measure greater than 90°.

b.The sum of the measures of the other two angles is 135°.

Step-by-step explanation:

Given : The measure of one interior angle of a triangle is 45°.

To find  :  What can you conclude about the other two interior angles of the triangle?

Solution : We have given that one interior angle of a triangle is 45°.

As we know that sum of all angle of a triangle is 180°.

Then we can say other angle may be acute or obtuse or right angle .

Since option a , c , d are wrong .

But , By angle sum property we can say sum of other two angles is 135.

Because 135 + 45 = 180

Therefore, b.The sum of the measures of the other two angles is 135°.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
