The answer would be -14<span>√2 or the decimal form is 19.79898987...</span>
angle EPF = angle DPG
=> 4x + 48deg = 7x
=> 3x = 48 deg
=> x = 16
=> angle EPF = 4(16) +48 = 112deg
A. When you solve for y, you will come out with x=0.1039, and x=-1.6039.
Step-by-step explanation:
x-25= 6x-5
-5x = 20
x=-4
First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
