Answer:
12 sqrt(2)
Step-by-step explanation:
Givens
a = 12 cm
b = 12 cm
c = ??
The triangle is isosceles with 1 right angle and 2 45 degree angles.
Formula
c^2 = a^2 + b^2
c^2 = 12^2 + 12^2
c^2 = 144 + 144
c^2 = 288
c^2 = 144 * 2
c = sqrt(144) * sqrt(2)
c = 12 * sqrt(2)
The answer isn't there. 12*sqrt(2) is the correct answer, 12sqrt(3).
Was this just a typo of some kind.
Answer:

Step-by-step explanation:
The tangent ratio is the ratio of the length of the opposite side to the length of the adjacent side.
This implies that;

The length of the side opposite to the 74 degree angle is 24 units.
The length of the side adjacent to the 74 degree angle is 7 units.
We substitute these values into the formula to obtain;

The correct answer is option F
Answer:
d
Step-by-step explanation:
17+15+b = 180 so If you do 180-(15+17) =b
Well we know 15+17 is 32 so now you do 180-32 which equals 148 so b=148
I think its is 4/5 but not positive
