Answer:
19
Step-by-step explanation:
The triangle is an isosceles and so angle SRT and angle STR are equal
also:
Angle SRT and angle STU are supplementary so their sum is equal to 180
7x + 2x + 9 = 180 add like terms
9x + 9 = 180 subtract 9 from both sides
9x = 171 divide both sides by 9
x = 19
8/25....." / " simply means division
so 8 divided by 25 = 0.32
I saw the figure of the pie. It is a circle with 8 slices. 4 slices are shaded, the other 4 are not.
So 4/8 or 1/2 of the pie is left.
Mr. Vargas eats 1/4 of the whole pie.
8 slices * 1/4 = 8/4 = 2 slices.
Out of the 4 slices remaining, Mr. Vargas ate 2 slices.
That left 2 slices from the original 8 slices.
2/8 = 1/4 of the pie remained.
