Answer:
9
Step-by-step explanation:
If the sine of an angle is equal to the cosine of an angle, that means that the sides adjacent and opposite to that angle are equal. One triangle that has two equal sides is an isosceles triangle. We can set this triangle to be a 45-45-90 degree triangle, which means that the angle would be 45.
Now, we have to find the value of
and
The tangent of 45 is 1, so 1 squared times 4 is 4.
We have .
Again, the tangent of 45 is 1, and 1 times 5 is 5.
We have
5 + 4 = 9
Answer:
The square of this expression is written as ( a − b ) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically. In mathematics, this algebraic identity is used as a formula and it is called in the following three ways. The square of difference of the terms formula.

Answer:
Take 4.25 x 8.6= 36.55 feet^2
Step-by-step explanation:
Answer:
8x4=32 or 8×4
Step-by-step explanation:
it's 32 because you are asking 8 time as many as 4 which is 8x4 or 8x4=3
