Answer:
D) 44°
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
y + y = 88
2y = 88
y = 44
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
We have a=10, b=14 and c=18
a² + b² = 10² + 14² = 100 + 196 = 296
and
c² = 18² = 324
296 < 324 ⇒ obtuse triangle.
I believe it would be C<span />
Answer:
23
Step-by-step explanation: Substitute 1 for p & 7 for q
7 − 5p + 3q
7 - 5(1) + 3(7)
7 - 5 + 21
7 + 16
23
