It takes 3 30 degree angles to make 90 degrees and 2 90 degree angles to make 180 degrees. So it would take 6 30 degree angles to make 180 degrees.

∠EFG and ∠GFH are a linear​ pair, m∠EFG=3n+23​, and m∠GFH=2n+32. What are m∠EFG and m∠​GFH?
NARA [144]

the measures of the angles are:

  • m∠EFG = 98°
  • m∠GFH = 82°
<h3>How to find the measures of the angles?</h3>

Two angles are a linear pair if their measures add up to 180°.

Then we will have that:

∠EFG + ∠GFH = 180

Here we know that:

m∠EFG=3n+23

m∠GFH=2n+32

Replacing that we get:

3n + 23 + 2n + 32 = 180

5n + 55 = 180

5n = 180 - 55 = 125

n = 125/5 = 25

Then the measures of the angles are:

m∠EFG=3n+23 = 3*25 +23 = 98°

m∠GFH=2n+32 = 2*25 + 32 = 82°

If BE=9cm, find GE<br> What is the answer
Sladkaya [172]

Answer:

GE = 3 cm

Step-by-step explanation:

BE = 9 cm

Since G is the centroid, therefore:

GE = \frac{1}{3}(BE) => Centroid theorem

Plug in the value

GE = \frac{1}{3}(9)

GE = 3 cm

What is the difference of the whole number and the mixed number below? 8-2 7/8 A. 6 7/8 B. 6 1/8 C. 5 7/8 D. 5 1/8
Mariana [72]

Answer:

D. 5 1/8

Step-by-step explanation:

First, convert the mixed number into an improper fraction

8-2 7/8 = 8- 23/8

Calculate the difference

8-23/8 = 41/8

Simplify the fraction

41/8 = 5 1/8

The question is in the picture
Veronika [31]

13 3/4 + x = 7 1/4

becomes x = 13 3/4 / 7 1/4

13 3/4  = 55/4

7 1/4 = 29/4

55/4 / 29/4 = 55/4 * 4/29 = 220/116

220/116 reduces to  1 26/29
