Thepotemich [5.8K]

Answer:

$1\frac{7}{8}\ in$

Step-by-step explanation:

step 1

Convert mixed numbers to an improper fractions

7.15h tire

$6\frac{5}{8}\ in=\frac{6*8+5}{8} =\frac{53}{8}\ in$

7.15h tire

$4\frac{3}{4}\ in=\frac{4*4+3}{4} =\frac{19}{4}=\frac{19*2}{4*2}=\frac{38}{8}\ in$

step 2

Find the difference

$\frac{53}{8}\ in-\frac{38}{8}\ in=\frac{15}{8}\ in$

step 3

Convert to mixed number

$\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\ in$

Grade 8 Math

Add 31 to both sides.

Since you brought the 9n over to the left side you have to get rid of other numbers that aren't n on that side

So you add the 31 to both side to remove it from the left

BRAINLIESTT ASAP! PLEASE HELP ME :)

Darina [25.2K]

Answer:

○ $\displaystyle h ≈ 29,3$

Step-by-step explanation:

You would normally use the Pythagorean Theorem for right triangles, but since you are only given one side, you must use the Law of Sines to define as many parts of the triangle as you can, to get the length of side h:

180° = 34° + 90° + m∠H

180° = 124° + m∠H

- 124° - 124°

_______________

$\displaystyle 56° = m∠H$
