Hey!
For 45-45-90 triangles you use you use the formula L(on the square root of)2
L represents the legs.
So you plug in
3(on the square root of)2 times (the square root of)2
You multiply the square roots to get
3(on the square root of)4
You simplify the square root of 4 to 2
So 3 times 2 = 6
So 6 is the answer
Hope this helped!
It’s the first one since they are equal by the side then the angle then again the side
Answer:
b=11 a=-2
Step-by-step explanation:
4=x and 7=y and 4+7=11
a(4)+3(7)=13
4a+21=13
-21 -21
4a=-8
÷4 ÷4
a=-2
We need the figure to solve it
