The question in English

Observe the following triangles. Make sure they are similar.

we know that

If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar.

In the triangle ABC

Find the angle C

the sum of the internal angles of a triangle is equal to 180 degrees

A+B+C=180

solve for C

C=180-(A+B)-------> C=180-(50+57)

C=73°

angle C=angle R

angle A=angle P

therefore

the answer is

triangles ABC and PQR are similar

A given line has the equation 2x + 12y = −1. What is the equation, in slope-intercept form, of the line that is perpendicular to

VikaD [51]

Answer:

y = 6x + 9

Step-by-step explanation:

The equation of a line in slope- interceot form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x + 12y = - 1 into this form

Subtract 2x from both sides

12y = - 2x - 1 ( divide all terms by 12 )

y = - $\frac{1}{6}$ x - $\frac{1}{12}$ ← in slope- intercept form

with slope m = - $\frac{1}{6}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{1}{6} }$ = 6

Note the line passes through (0, 9) on the y- axis ⇒ c = 9

y = 6x + 9 ← equation of perpendicular line

Brittney has 2 and 3/4 yards of fabric. She wants to make wreaths that require 1/8 yards. What is the maximum number of wreaths

vlabodo [156]

Answer: 22

Step-by-step explanation:

Given

Brittney has 2 and $\frac{3}{4}$ yards of fabric

Converting it to a fraction

$\Rightarrow 2\ \dfrac{3}{4}=\dfrac{8+3}{4}\\\\\Rightarrow \dfrac{11}{4}$

Wreath require $\frac{1}{8}$ yards

Number of wreaths that can be made

$\Rightarrow n=\dfrac{\frac{11}{4}}{\frac{1}{8}}\\\\\Rightarrow n=\dfrac{11}{4}\times \dfrac{8}{1}\\\\\Rightarrow n=22$

She can make 22 wreaths
