Find the Measure of each angle.

Mathematics
1 answer:
alina1380 [7]3 years ago
4 0

Answer:

x = 10

Step-by-step explanation:

to find the measure of angles we first need to find the value of x

The sum of interior angles in a triangle is equal to 180

9x + 7x + 2x = 180 add like terms

18x = 180 divide both sides by 18

x = 10 to find angle measures replace x with 10 in each representative like:

m<L = 9x and 9*10 = 90 and so on

What is the measurement of angle A to the nearest degree?
forsale [732]

Answer:

A = 51 degrees

Step-by-step explanation:

We can use the law of sines

sin A          sin 95

------------ = -----------

7                   9

Using cross products

9 sin A = 7 sin 95

Divide each side by 9

sin A = 7/9 sin 95

Take the inverse of each side

sin ^-1 sin A = sin ^-1 ( 7/9 sin 95)

A = 50.78854367

To the nearest degree

A = 51 degrees

How to solve this system of equation 3x + y= 17 and 4x + 2 y = 20
lana66690 [7]
<span>3x + y= 17        (a)
4x + 2 y = 20    (b)

Multiply (a) by 2:

6x + 2y = 34   (a)
4x + 2y = 20   (b)

make:   (a) - (b)

2x = 14 -----> x =7

-------------------------------

Replace the value of x = 7 in one of anterior equation:

</span>3x + y= 17  
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4
