Someone please help me, i really need it. I'll award brainliest please :(
mario62 [17]

Answer:

150 degrees

Step-by-step explanation:

The sum of all angles in a pentagon is 540 degrees. So you add the measurements of the 4 you know - 95 + 95 + 100 + 100 = 390. Then you subtract 540 - 390 - 150 degrees for the last angle.

Exercise 21
Lina20 [59]

Answer:

see explanation

Step-by-step explanation:

area of Δ ABC is calculated as

A = \frac{1}{2} bh ( b is the base and h the height )

Here b = 4x - 6 and h = 2x - 3 , then

A = \frac{1}{2} (4x - 6)(2x - 3) ← expand using FOIL

   = \frac{1}{2}(8x² - 24x + 18) ← distribute

    = 4x² - 12x + 9

----------------------------------------------------------

Area of rectangle CBFG is calculated as

A = lb ( l is length, b is breadth )

Here l = 4x - 6 and b = 3x - 2, then

A = (4x - 6)(3x - 2) ← expand using FOIL

   = 12x² - 26x + 12

----------------------------------------------------------

Area of trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂)

where h is the height and b₁, b₂ the parallel bases

Here h = 2x - 3, b₁ = 4x + 1, b₂ = 2x + 3 , then

A = \frac{1}{2} (2x - 3)(4x + 1 + 2x + 3)

   = \frac{1}{2} (2x - 3)(6x + 4) ← expand using FOIL

   = \frac{1}{2} (12x² - 10x - 12) ← distribute

   = 6x² - 5x - 6
