Answer:
19
Step-by-step explanation:
Angle ZYW is congruent to angle YWX, so the 3 angles must add to 180.
(3x - 5) + 90 + 2x = 180
5x + 85 = 180
5x = 95
x = 19
Square root of 154m^2 = 12.5~
So adding 1.5 to 12.5 and subtracting 1.5 to 12.5 gives us 11 and 14
Your dimensions are 11x14

Answer:
She should have multiplied one half (4)(3.5) by 5 squared.
Step-by-step explanation:
We are given that
Base of triangle=b=4 cm
Height of triangle=h=3.5 cm
Area of triangle=
After enlarged
Scale factor=5
New base of enlarged triangle=b'=4(5) cm
Height of enlarged triangle=h'=3.5(5) cm
Area of enlarged triangle=

She should have multiplied one half (4)(3.5) by 5 squared.
We have the formula A = (h x b) / 2, where A is the area of the triangle, h is the height of the triangle, b is the base of the triangle;
So, 32 =(8 x b) / 2;
Then, 64 = 8 x b;
b = 64 ÷ 8;
b = 8 inches;
