Answer:
side length each 5√2
Step-by-step explanation:
both legs have the same length, as the triangle is a 45 - 90 45
To find one side of the triangle us the cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(A)=adj/hyp
cos(A)=adj/10
adj=cos(A) * 10
adj = 5√2
(-4)^-6*(-4)^7 = (-4)^1 = -4
answer a. -4
Negative 1 because 3 x 3 is 9 and -2 x 5 is -10. Therefore 9-10= negative 1
