No because a triangle is 180 degrees and the following angles only equal to 165
Answer:
∠C' = 66°
Step-by-step explanation:
Because triangles ABC and A'B'C' are similar, their angles are still the same; only their side lengths are different, though still proportionate.
Hence, ∠A = ∠A', ∠B = ∠B', and ∠C = ∠C'.
Here, we're given that ∠A = 68, which means ∠A' = 68; we also know that ∠B = 46, so ∠B' = 46.
We want to find C', so remember that all angles in a triangle sum to 180:
∠A' + ∠B' + ∠C' = 180
68 + 46 + ∠C' = 180
114 + ∠C' = 180
∠C' = 66°
It could be 2.5+2.5=5 and then add that to 4 and that equals 9
Answer:
(77, 77)
Step-by-step explanation:
Carry out the indicated multiplication:
3(-0.8, 6.3) → (-2.4, 18.9)
Next, combine like terms:
(79.4, 58.1) + (-2.4, 18.9). In other words, combine the x terms 79.4 and -2.4 separately and then the y terms 58.1 and 18.9 separately:
(79.4, 58.1) + (-2.4, 18.9) → (77, 77)
Answer:
( 7x + 11 )( 7x- 11 )
Step-by-step explanation:
( 7x + 11 )( 7x- 11 )
Because 7*7 is 49
-11*11= -121
7*11=77
-7*11= -77
77-77=0
so the answer is 49x^2-121
