The answer is 25.5 cm2

area of rectangle = LW = (7)(3) = 21

area of triangle on left side = 1

bh = 1

(8 − 7)(3) = 1

(1)(3) = 1.5

area of triangle on right side = 1

bh = 1

(2)(3) = 3

Therefore, trapezoid area = 21 + 1.5 + 3 = 25.5 cm2

A Triangle has an angle that measures 137.3 degrees. The other two angles are in a ratio of 3:4. What are the measures of those

Andreyy89

So we start off by subtracting 137.3 from 180 getting 42.5. If you add the ratios up (3+4) you get 7 and 7 should equal 42.5. thus,

42.5/7= 85/14

(85/14)*3=18.2 or (255/14 to be exact)
(85/14)*4= 24.29 or (170/7 to be exact)

<h3>What is a Quadratic Equation?</h3>

Quadratic equations are the polynomial equations of degree 2 in one variable of the type $f(x) = ax^{2} + bx + c = 0$ where a, b, c, ∈ R and a ≠ 0.
The standard form of a quadratic equation is $ax^{2} + bx + c = 0$ .
