Answer:
x = 11.3
Step-by-step explanation:
This is a right isosceles triangle
x² + x² = 16²
2x² = 256
x² = 128
x = 11.3
Answer:
Step-by-step explanation:
AB is equal to AC
so x + 7 = 2x - 1
then simplify
7 = x - 1
x = 8
plug it back into AB
8 + 7 = 15
so AB is 15
9514 1404 393
Answer:
x = 25; ∠3 = ∠6 = 60°
Step-by-step explanation:
Angles 3 and 6 are alternate interior angles, so are congruent.
2x +10 = 3x -15
25 = x . . . . . . . . . . . add 15-2x
2x +10 = 2(25) +10 = 60
The measures of angles 3 and 6 are 60°.
Answer:
3(4a + 2b)
Step-by-step explanation:
if we were to expand this back out then we would get 12a + 6b
3 x 4 = 12 then add the a (12a)
3 x 2 = 6 then add the b (6b)
then your plus sign and you have your original ancwer meaning that this problem is correct
