I solved this rational equation by combining expressions and isolating the variable a
a = -2
Step-by-step explanation:
∠A + ∠B + ∠C = 180°
Here the value of ∠B and C is given below...we need to find the value of ∠A ....
a + 120° + 40° = 180°
a + 160° = 180°
a = 160° - 180°
a = 20°

Answer:
HL
Step-by-step explanation:
The triangles are right triangles, opening the possibility of using the special right-triangle congruence theorems.
The hypotenuses are marked congruent, and one leg is shared. No angles (except the right angle) are marked congruent. With only two sides and one angle, the AAS, SSS, and ASA theorems cannot apply.
The HL theorem can be used to show the triangles are congruent.
