This triangle is an isosceles triangle (as indicated by the tick marks through the two sides). The base angles of isosceles triangles are congruent; this means the measure of angle x is congruent to the measure of the unlabeled interior angle.
The sum of the interior angles of all triangles is 180 degrees; you can find x by setting the sum of the two unknown angles, x, and 98 equal to 180 and solving algebraically.
180 = 98 + x + x
180 = 98 + 2x
82 = 2x
41 = x

Answer:
35 nachos sold and 52 sodas sold
Step-by-step explanation:
let x represents number of Nachos sold
let y represents number of Sodas sold
We are given two equations, so we can combine them to solve for one variable at a time.
Equation 1: x + y= 87 (because total of both sold was 87 items)
Equatiom 2: 1.50 x+ 0.50 y = 78.50 (1.5 times number of nachos, plus 0.50 times number of sodas equals 78.50)
So, y = 87 - x (transpose the n from the first equation)
Take (87 - x) for y in the equation 2
1.50 x + 0.50 (87 - x) = 78.50
1.50 x + 43.50 - 0.50 x = 78.50
1.50 x - 0.50 x + 43.50 = 78.50
x + 43.50 = 78.50
x = 78.50 - 43.50
x = 35
To get the y
y = 87 - 35
y = 52
