Answer:

y = 12.3 cm

Step-by-step explanation:

Since the triangle is right with hypotenuse 15, use the cosine ratio to solve for y, that is

cos35° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{15}$

Multiply both sides by 15

15 × cos35° = y, hence

y ≈ 12.3

M is the midpoint of PQ, N is the midpoint of MQ, and L is the midpoint of MN. IfPQ = 64, find LN.

alisha [4.7K]

LN=8 because every time there is a midpoint you have to divide it in half. So 64,32,16,8

Surface area of this right prism

Sphinxa [80]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textsf{Let's calculate the surface area of given right prism}$

$\textbf{Area of Triangles :}$

$\sf{\dfrac{1}{2}\cdot 16\cdot 12}$

$\sf{8×12}$

$\sf96 \: \: cm {}^{2}$

$\textsf{Since there are two triangles, }$

$\textsf{Area of Triangles = 96 × 2 = 192 cm²}$

$\textbf{Now, calculate the Areas of rectangles :}$

$\textsf{Area - 1 = 12 × 10 = 120 cm²}$

$\textsf{Area - 2 = 16 × 10 = 160 cm²}$

$\textsf{Area - 3 = 20 × 10 = 200 cm²}$

$\textsf{Now add them all :}$

$\textsf{120 + 160 + 200 + 192}$

$\textsf{672 cm²}$
