Answer:
∠2 = 115.5°
Step-by-step explanation:
128.5° is an exterior angle of the triangle
The exterior angle equals the sum of the 2 opposite interior angles, hence
∠2 + 13 = 128.5 ( subtract 13 from both sides )
∠2 = 115.5°
The answer is 10
Because of the Pythagorean theorem, for sides of a right triangle (a triangle with one 90 degree angle) a, b, and c, where c is the hypotenuse (the side opposite the 90 degree angle), a^2 + b^2 = c^2.
We have a and b given in this problem, 6 and 8. We are solving for c. So 6^2 + 8^2 = c^2.
6^2 = 36, 8^2 = 64. 36 + 64 = 100. So c^2 = 100. The square root of 100 is 10, so c = 10.
Answer:
The answer is C
Step-by-step explanation:
I used Math-way
An exterior angle is equal to the sum of the two opposite inside angles.
T + 31 = t + t-29
Simplify:
T + 31 = 2t -29
Add 29 to both sides:
T + 60 = 2t
Subtract 1t from both sides:
T = 60
Answer:
625: 1296
Step-by-step explanation:
625: 1296 cannot be further simplified because they share no common factor. The decimal form around 0.5822531
