Answer: It is said to be an obtuse angle.
Step-by-step explanation:
Angles under 90 degrees are called acute angles.
Angles that are equivalent with 90 degrees are right angles.
Angles that measure more than 90 degrees but under 180 degrees are called obtuse.
Angle that have the same measure as 180 degrees are straight angle.
Yes because the y intercept would be a different value for the new equation unless it is zero
Answer:
t = 0
Step-by-step explanation:
(7t - 2) - (-3t + 1) = -3(1 - 3t)
because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally
[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]
will be
7t - 2 + 3t - 1 = -3 + 9t
add like terms
10t - 3 = -3 + 9t
subtract 9t from both sides
t - 3 = -3
add 3 to both sides
t = 0
Answer:
Step-by-step explanation:
complimentary angles, when added = 90 degrees
69 + 5n + 1 = 90
5n + 70 = 90
5n = 90 - 70
5n = 20
n = 20/5
n = 4 <====
