Can you help me out

The base of trapezoid is equal to a = 25.5 cm and b = 43.5 cm.

The area of trapezoid is A = 1656.

The formula for the area of trapezoid is,

$A=\frac{a+b}{2}\cdot h$

Substitute the values in the formula to obtain the height of trapezoid.

$\begin{gathered} 1656=\frac{25.5+43.5}{2}\cdot h \\ h=\frac{1656\cdot2}{69} \\ h=24\cdot2 \\ =48 \end{gathered}$

So height of trapezoid is 48 cm.

N - 29 - 33 = -49 solve the equation.

Pepsi [2]

Answer:

n=13

Step-by-step explanation:

n-29-33=-49

Always work left to write in these types of equation, so subtract -29-33 to get -62:

n-29-33=-49

n-62=-49

Add 62 to both sides:

n-62=-49

+62 <u>+62</u>

n = 13
