Data:

l and m are parallel lines

QR and ST are perpendicular in R

Angle 1 is 63°

The angle formed by perpendicular lines is a right angle (90°)

Angles 1 and 3 are alternate angles: angles that occur on opposite sides of a transversal line that is crossing two parallel.

Alternate angles are congruent, have the same measure.

\begin{gathered} m\angle1=m\angle3 \\  \\ m\angle3=63 \end{gathered}

The sum of the interior angles of a triangle is always 180°. In triangle QRT:

\begin{gathered} m\angle2+m\angle3+90=180 \\  \\ m\angle2+63+90=180 \\  \\ m\angle2+153=180 \end{gathered}

Use the equation above to find the measure of angle 2:

\begin{gathered} \text{Subtract 153 in both sides of the equation:} \\ m\angle2+153-153=180-153 \\  \\ m\angle2=27 \end{gathered}Then, the measure of angle 2 is 27°

Answer:

The slope is 3/2 and the y intercept is 4

Step-by-step explanation:

We want to write in the form

y = mx+b where m is the slope and b is the y intercept

-3x+2y = 8

Add 3x to each side

-3x+3x+2y = 3x+8

2y = 3x+8

Divide each side by 2

2y/2 = 3x/2 + 8/2

y = 3/2x +4

The slope is 3/2 and the y intercept is 4

they've invested to earn $20 in a savings account that offer 3% return on the investment the value of david's investment will be
Firlakuza [10]
I=PRT
P=present amount
R=rate
T=time
basically
20+interest<u /> is more than or equal to 400
20+I<u>></u>400
minus 20 both sides
I<u>></u>380

solve
P=20
R=3%=0.03
T=?
I=PRT
380<u><</u>I=PRT
380<u><</u>20(0.03)(T)
380<u><</u>0.6T
divide both sides by 0.6
633.33333<u><</u>T

Josh has a rewards card for a movie theater. - He receives 15 points for becoming a rewards card holder. - He earns 3.5 points f
jeka94

Answer:

Option A. 3.5x + 15 ≥ 55

Step-by-step explanation:

Points Rosh received for becoming a member = 15

Points Rosh received for visiting the moving theater = 3.5

Total points needed for a free movie ticket = 55

For each visit he receives 3.5 points, so for x visits he will receive 3.5x points.

Total points = Points received on becoming a member + Points received on x visits

So,

Total Points = 15 + 3.5x

These points must be at least 55 for a free movie ticket. At least means equal to or greater than. So the total points must be equal to or greater than 55 in order to earn a free movie ticket. This can be expressed as:

3.5x + 15 ≥ 55

So, option A gives the correct answer
