The answer would be D. 56in^2
Answer: y=4
Step-by-step explanation:
This is a 45-45-90 triangle. It is also a special triangle. The hypotenuse is x√2. X is sommon through all 3 sides. The legs of the triangle are x in length each.
Looking at the picture, we see the hypotenuse is equal to 4√2. We can set this equal to the hypotenuse to find what x is.
4√2=x√2
x=4
Since we know that the legs of the triangle are both equal to x, we knoe that y=4.
Answer:
Angle 1 = 70, Angle 2 = 90, Angle 3 = 70, Angle 4 = 70
Step-by-step explanation:
1. 90 -20 = 70
2. Diagonals are perpendicular and create right angles that equal 90
3 and 4. Diagonals bisect angles, angles on opposite sides are congruent
Answer:
y = x ÷ x
Step-by-step explanation:
x = 13
y = 13 ÷ 13
y = 1
so y = x ÷ x
(4x+7) (x^2+1) is it factored
