Answer:

x=49\degree,y=6

Step-by-step explanation:

Angle x corresponds to the complement of the 41\degree in the bigger triangle. See diagram in attachment.

This implies that,

x=90-41=49\degree


Also since the triangles are similar, the sides are in the same proportion.

This implies that,

\frac{3y-8}{15}=\frac{4}{6}


We multiply both sides by 15 to get,

3y-8=\frac{4}{6}\times 15


\Rightarrow 3y-8=\frac{2}{3}\times 15


\Rightarrow 3y-8=10


\Rightarrow 3y=10+8


\Rightarrow 3y=18


We divide through by 3 to get,

y=6


The correct answer is D

4:3 and 25:45 are equal ratios true or false
kondaur [170]
False.

The scale factor for 3 and 45 is 15.

45 / 3 = 15.

We know that 25 isn't even a whole number for the scale factor, because no number x 4 can equal 25 (whole numbers only).

25 / 3 = 6.33333

The height of a triangle is 4 times its base. The area of the triangle is 288 square. Find the base and the height of the triang
Vanyuwa [196]
\bf \textit{area of a triangle}\\\\
A=\cfrac{1}{2}bh\qquad 
\begin{cases}
b=base\\
h=height\\
----------\\
h=4b\leftarrow 
\begin{array}{llll}
\textit{height is 4}\\
\textit{times the base}
\end{array}\\
A=288
\end{cases}\implies 288=\cfrac{1}{2}\cdot b\cdot 2b

solve for "b", to see what the base is

what about the height?  well, h = 4b
