Aright isosceles triangle has an angle with measure of 45°. if x represents the measure of the third angle of the triangle, what is x?

  x = 45°

Step-by-step explanation:

"Isosceles" means the base angles are congruent: they both have the same measure, 45°. (The hypotenuse is the "base" for this isosceles triangle.)

The acute angles of a right triangle are complementary, so the third angle can also be found as 90° -45° = 45°.

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
