Answer:

c. 28

Step-by-step explanation:

Use Pythagorean theorem to find the leg of the right triangles.

a² + 12² = 15²

a² + 144 = 225

a² = 81

a = 9

So the value of x is:

x = 9 + 10 + 9

x = 28

6. Find QR, if area and altitude PS of ∆PQR are given<br> ar(∆PQR) = 180 cm2, PS = 15​
Slav-nsk [51]

Given:

Area and altitude PS of ∆PQR are ar(∆PQR) = 180cm² and PS = 15​.

To find:

The measure of side QR.

Solution:

According to the given information, PS is an altitude of ∆PQR. It means QR is the base of ∆PQR.

We know that, the area of a triangle is

Area=\dfrac{1}{2}\times Base\times Height

ar(\Delta PQR)=\dfrac{1}{2}\times QR\times PS

Substituting the given values, we get

180=\dfrac{1}{2}\times QR\times 15

180\times 2=QR\times 15

360=QR\times 15

Divide both sides by 15.

\dfrac{360}{15}=QR

24=QR

Therefore, the measure of side QR is 24 cm.

Sort each equation according to whether it has one solution, infinitely many solutions, or no solution.
Aliun [14]
《ANSWER》

《LINEAR EQUATIONS》

Solving all we get as

↪1) 5 (x -2) = 5x - 7

since after solving X is cancelled , NO SOLUTION

↪2) -3 (x - 4) = -3x + 12

SINCE after solving X is any value , infinitely many solutions

↪3) 4 (x + 1) = 3x + 4

solving we get as , 4x+ 4 = 3x + 4 =》 X =0

only one solution

↪4) -2 (x-3) = 2x - 6

Only one solution

↪5) 6 (x + 5) = 6x + 11

NO SOLUTION

All the equations are solved by the distributive law of algebra

PLSSS HELP ME!!!!!!!
DanielleElmas [232]

Answer:

y=15

Step-by-step explanation:

Because of the exterior angle theorem angle A plus angle b or equal to 146.

so you set 5y+3+4y+8=146 and solve

5y+3+4y+8=146

9y+11=146

9y=135

y=15
