What is the measure of angle A in the triangle? Enter your answer in the box. mZA=

stepladder [879]

Answer:

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

A + B + C = 180

2x-10 + 70+ x+30 = 180

Combine like terms

3x +90 = 180

Subtract 90 from each side

3x+90-90=180-90

3x= 90

Divide by 3

3x/3= 90/3

x=30

We want to find angle A

A = 2x-10

=2*30 -10

=60-10

Which ratio is equivalent to 3/7? A) 6 to 10 B) 9:12 C) 12/35 D) 7 to 3

Leona [35]

we are ratio as

$=\frac{3}{7}$

It will be equivalent to only those terms which would be multiple of this term

so, we will multiply top and bottom term by 5

and we get

$=\frac{3\times 5}{7\times 5}$

$=\frac{15}{7\times 5}$

$=\frac{15}{35}$

so, it is very similar to 12/35

so, it will be equivalent to 12/35

so, option-C.......Answer
