Hope it helps!
Step-by-step explanation:
Answer: Yes
Step-by-step explanation: Let's first find the missing angle in the second triangle and to find this angle, remember that the sum of the measures of a triangle is 180 degrees so you should find that our missing angle is 67°.
Now, notice that we have two angles and the included side of one triangle
congruent to two angles and the included side of a second triangle.
Therefore, we can say the triangles are congruent by ASA.
Answer:
408 in²
Step-by-step explanation:
A rectangular prism has 6 rectangular faces.
Opposite faces are congruent
2 faces at (6 × 9) = 2 × 54 = 108 in²
2 faces at (9 × 10) = 2 × 90 = 180 in²
2 faces at (6 × 10) = 2 × 60 = 120 in²
surface area = 108 + 180 + 120 = 408 in²
