Answer:
69°, 69°, and 42°
Step-by-step explanation:
Isosceles triangles have three angles -- one vertex angle and two base angles.
The <u>base angles have the same measure</u> and the vertex angle has a different measure.
<u>Remember all triangles' interior angles sum to 180°.</u>
If the vertex angle is 42°, then the two base angles combined are:
180° - 42° = 138°
Since the base angles are the same, <u>each base angle is:</u>
138° ÷ 2 = 69°
Therefore the angles in the triangle measure 69°, 69°, and 42°.

Answer:
h= -144
Step-by-step explanation:
Answer:
x = - 9, x = 0, x = 7
Step-by-step explanation:
Given
x(x - 7)(x + 9) = 0 ← in standard form
Equate each factor to zero and solve for x
x = 0 ⇒ x = 0
x - 7 = 0 ⇒ x = 7
x + 9 = 0 ⇒ x = - 9
