PART A:
The option that would be equal to figure ABC would be A scalene triangle with only one angle that measures 80* because the other angle is not shown in this phrase so we could say that the other angle is 50* then it would be equal to figure ABC, and a scalene triangle is a triangle with three uneven, unequal sides,
Therefore the answer would be,
C. A scalene triangle with only one angle that measures 80*
Y - 2 = 1/2 * ( x - 3 )
hope this helps!
Answer:
drag 10 to the
Step-by-step explanation:
2(-3n-5)-5(4n-8)
(-6n-10)+(-20n+40)
-26n-30
(a) 95 = (x+7)*(x-7)
(b) 95 = (x+7)*(x-7)
Expand the brackets:
95 = x² -7x + 7x -49 = x² - 49
Subtract x² from both sides:
95-x² = -49
Subtract 95 from both sides:
-x²=-49-95
-x²= -144
Divide both sides by -1 to get rid of the negative numbers:
-x²/-1=-144/-1
x²=144
Take the square root of 144:
x = ± squareroot of 144
x = 12 or -12
x = 12 because you cannot have a negative age so Trina is 12 years old.
