Answer:
<em>x = 32</em>
Step-by-step explanation:
This is an isosceles triangle since two sides have length 10. The angles opposite the congruent sides are congruent. There is an angle measuring 116 deg, and two angles measuring x. The sum of the measures of the angles of a triangle is 180.
x + x + 116 = 180
2x + 116 = 180
2x = 64
x = 32
Standard form is Ax + By = C
Your equation is y = 3/4 x + 1
3/4 x + 1 y = 1
The answer is 6.2857 you take all the values add them together then divide by the amount of values
Well If you mean't 15 1/2 it is 15.5 This is because a decimal is made for parting using place values like tenths, hundredths, thousandths, etc. The 1/2 part is is .5 because 5 is half of 10.
