The choose (C) 60
The measure of the angles of a triangle is 180, and this triangle is equilateral, so 180/3=60, each angle is 60°
Answer:21
Step-by-step explanation:
The kid makes 7 dollars an hour.
7*2=14
7*3=21
7*5=35
x+ y = 96 → y = 96 - x (1)
And the price per plain cake * the number he sold + price of the decorated cake * the number he sold = total sales
So
8x + 12y = 800 (2)
Subbing (1) into (2), we have that
8x + 12 (96 - x) = 800 simplify
8x + 1152 - 12x = 800
-4x + 1152 = 800 subtract 1152 from both sides
-4x = -352 divide both sides by -4
x = 88 = the number of plain cakes he sold
And 96 - x = 96 - 88 = 8 = the number of decorated cakes he sold
Answer:
69°
Step-by-step explanation:
if CA and AT are congruentsides, this means that the angle of C and T must also be the same.
In order for a triangle to be a triangle, they must meet the angle of 180 degrees.
We know CAT is = to 42
So we subtract 42 from 180 = 138 degrees
we then divide 138 by 2 and we get 69
angles c + t are both 69 degrees
