Answer: 11.4
Step-by-step explanation: In the fraction 57/5, 57 is the numerator and 5 is the denominator, the fraction bar means "divided by". Therefore, the fraction 57/5 is same as "57 divided by 5" or "57 ÷ 5".
When we calculated 57 divided by 5, we found that 57/5 in decimal form is:57 ÷ 5 = 11.4 Therefore, the decimal form of 57/5 is 11.4
Hope I helped <3
Create a ratio and cross multiply
20x - 75 = 14x + 63
6x = 138
x=23
hope this helps :)
The angles of a triangle should add up to 180 degrees. in the left triangle, you should find the 3rd angle
75 + 50 + y = 180
125 + y = 180
y = 55
vertical angles are congruent, so the left angle on the right triangle will also be 55 degrees.
then you do the same thing to find x.
85 + 55 + x = 180
140 + x = 180
x = 40
Answer:
m∠S = 29.5
Explanation:
Q
S 
R
In this triangle, QR = SQ, which means its an isosceles triangle, angle S and R is similar.
<u>Thus solve:</u>
m∠S = (180° - 121°)/2
m∠S = 29.5°
