Answer:
∠ 1 = 120°
Step-by-step explanation:
5x + 15 and 3x - 3 are same- side interior angles and sum to 180° , then
5x + 15 + 3x - 3 = 180 , that is
8x + 12 = 180 ( subtract 12 from both sides )
8x = 168 ( divide both sides by 8 )
x = 21
Then
5x + 15 = 5(21) + 15 = 105 + 15 = 120
∠ 1 and 5x + 15 are corresponding angles and are congruent , so
∠ 1 = 120°

Answer:
Step-by-step explanation:
Use ^2 to indicate ²
y = (x-3)² + 8
This is an up-opening parabola.
Vertex (3,8)
Axis of symmetry: x = 3
Domain: ℝ
Range: [8,+∞)
To be able to fine one of the bases we must first find the vertex and to do that we have to find the value of a.
A triangle measures 180 degrees.
Therefore we must form an equation that is equal to 180 degrees.
(a + 30) + 2(2a - 15) = 180
We put 2 in front of (2a - 15) because there are two base angles.
Solution:
(a + 30) + 2(2a - 15) = 180
a + 30 + 4a - 30 = 180
a + 4a + 30 - 30 = 180
5a = 180
5a/5 = 190/5
a = 36 degrees
Therefore the base = 2(36) - 15 = 57 deg
