8 bc 2/3 x 18= 12 and 12-4 = 8 :) sorry if im wrong tho
C. 10 m because 10 times 10 is 100 m^2 which is the area. hope that helps!
The proof shows that x is equal to the sum of the interior adjacent angles
<h3>Sum of interior and exterior angle of a triangle</h3>
From the given triangle:
x + y = 180 (sum of angle on a straight line is 180 degrees)
Also, the sum of an interior angle of the triangle is 180 degrees, hence:
y + 50 + 70 = 180
Equate both expressions
x + y = y + 50 + 70
x + y - y = 50 + 70
x = 50 +70
This shows that x is equal to the sum of the interior adjacent angles

Answer:
x/50=78/100
Explanation:
since the test has 50 points TOTAL, you know that it will be the denominator. and x would be however many points he got on the test. so out of 50 points, the student got x points is what x/50 means. then the second one would be your percentage. when converting percents do decimals, the number of your percent (in this case 78) would be your numerator, and since percents are out of 100 your denominator would be 100
