I don't know what your looking for, so be more specific, but I'm assuming your solving for x, so that's would be
x = -1
7) • A straight line is 180 deg
• So B = 180-138 = 42 degrees
• Isosceles triangles have equal angles on the equal sides
• So G = 42 degrees
• We know a triangle has 180 degrees
• So 180 - 42 - 42 = 96 degrees for A
8) • Use similar logic to above
• TCB = 180 - 87 = 2x
• TCB = 46.5 degrees
• ACB = 180 - 65 = 2x
• ACB = 57.5 degrees
• TCB + ACB = ACT = 104 degrees
Answer:
B
Step-by-step explanation:
You need to subtract 1.00 from the sum of 0.25 and 0.30, which is 0.55, and that is your change, $0.45
If your'e surface area is 990cm2 then your height value is 247.5 tall i think not sure if not keep dividing 247.5 into 4 till you have a choice that is a divisible by 4
