Step-by-step explanation:
Given is a 45°-45°-90 ° angled triangle.
By 45°-45°-90 ° angled triangle theorem:
side opposite to 45° angle is
times of hypotenuse.

Answer:
4t^3-t-4
Step-by-step explanation:
(-3t^3-5t)+(7t^3+4t-4)
Combine like terms
-3t^3+7t^3 +4t -5t-4
4t^3 -t -4
I am not so sure of this but I feel it would serve as hint
The answer is 50 minutes.
Explanation: 10*50=500, 1000-500=500
6*50=300, 800-300=500
<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
hope this helps :)
