Please explain how to do this im confused

70° , 70°

Step-by-step explanation:

The 2 angles are corresponding and are congruent, then

23x + 1 = 4 + 22x ( subtract 22x from both sides )

x + 1 = 4 ( subtract 1 from both sides )

x = 3

Then the angles are

23x + 1 = 23(3) + 1 = 69 + 1 = 70°

4 + 22x = 4 + 22(3) = 4 + 66 = 70°

70° & 70°

Step-by-step explanation:

These angles are known as corresponding angles. This means they are congruent.

23x + 1 = 4 + 22x

23x + 1 - 22x = 4 + 22x - 22x

x + 1 = 4

x + 1 - 1 = 4 - 1

x = 3

Substitute the value for the variable.

23(3) + 1 = 70

4 + 22(3) = 70

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

entering that problem on the tube might get you an answer
