H = 72°

k = 18°

m = 54

The measure of angle C is 108°. Angle C is a vertical angle along angle m and its adjacent angle. Furthermore, angle m and its adjacent angle to the right are congruent.

So, the equation used to find angle m is 2x = 108.

n = 62°

I think that r = 108° because it should be congruent to f because they look like alternate exterior angles.

Then, angles r and p form a linear pair so they are equal to 180°.

Knowing that r = 108°, p must be 72°.

Angle q, its consecutive adjacent angle to the left to which it's congruent to, and angle p all form a linear pair. So, 72 + 2q = 180. By simplifying this, we'll have q = 54°.

In order to find angle l, we need to understand that a triangle's total sum of interior angles is 180°.

18 + 72 + x = 180

90 + x = 180

x = 90

So, the measure of angle L is 90°.

Murrr4er [49]

Answer:

2 sets of possible solutions:

x=3, y = 5

and

x=-1, y = -3

Step-by-step explanation:

Using the graphical method, (see attached)

you can graph both equations and find their intersection points.

From the attached plot, you can see that the graphs intersect at (3,5) and (-1,-3)

Alternatively, you can solve this numerically by solving the following system of equations. You will get the same answer.

y = 2x + 1 ------------------- eq. (1)

y = x² - 4 ------------------- eq. (2)

ipn [44]

Answer:

3x

Step-by-step explanation:

50 mi/hr × (1 hr / 60 min) × (200 gal / 500 mi) = ⅓ gal/min

(⅓ gal/min) × (t min) = x gal

t = 3x

What is x/13-5=25/26
Juliette [100K]

\frac{x}{13} -5=\frac{25}{26}    Add 5 on both sides

\frac{x}{13}=\frac{25}{26}+5    Make the denominators the same

\frac{x}{13}=\frac{25}{26}+\frac{130}{26}

\frac{x}{13}=\frac{155}{26}    Multiply 13 on both sides

(13)\frac{x}{13}=(13)\frac{155}{26}

x=\frac{2015}{26}

x=\frac{155}{2}

The length of the hypotenuse of a 30-60-90 triangle is 28 m. Find the length of the side opposite the 30 angle
____ [38]
The answer is 14 m

<span>In a 30°-60°-90° triangle, the hypotenuse (c) is twice the length of the shorter leg (a) which is the opposite to the 30 angle:
</span>

c = 2a


We have c = 28 m

So: 28 = 2a

      a = 28 / 2 

     a = 14 m
