Answer:

64

Step-by-step explanation:

The surface of the triangle count formula

A = b*h*1/2

A - area

b - base

c - height

The first triangle

A₁ = b₁*h = 6in * 8in *1/2= 24in²

The second triangle

A₂ b₂*h = 10in * 8in*1/2 = 40in²

The total area of the two triangles is 24in² + 40in² = 64 square inches

     Long division:   (x³ + 2)  ÷  (x + 1)


                                        <u>    </u><u>x² –  x  +  1   </u>
      x³ + 0x² + 0x + 2      |    x  +  1
   <u>– x³ –   x²</u>    ⋮       ⋮
          –   x² + 0x     ⋮
          <u>+   x² +   x</u><span>     ⋮</span>
                    +  x + 2
<span>                   </span> <u>–  x – 1</u>
                            + 1


         Quotient:   Q(x) = x² – x – 1;
  
     Remainder:   R(x) = + 1.

In ABC the measure of angle A is 2x+4 , the measure of angle B is 4x+2 , and the measure of angle C is 2x-1. What are the measur
Lynna [10]
(2x+4)+(4x+2)+(2x-1)=180
8x+5=180°
8x=180-5
8x=175
X=21.875
A= 2(21.875)+4=47.75
B=4(21.875)+2 =89.5
C=2(21.875)-1=42.75
