Answer:
x = 31°
Step-by-step explanation:
All the angles given, a, 2x, and 3x, form a straight lines, so therefore, they add up to 180°. We can write an equation from the info:
a + 2x + 3x = 180°
We know a is 25°, so we can substitute that in:
25° + 2x + 3x = 180°
Combine like terms...
25° + 5x = 180°
And solve.
5x = 155°
x = 31°
Answer:
B, C, D
Step-by-step explanation:
4(4a + 5) = 16a + 20
Look at each answer individually.
A. 16a + 5 <u>This is not correct.</u>
B. 16a + 20 This is correct.
C. 12a + 20 + 4a = 16a + 20 This is correct.
D. 2(8a + 10) = 16a + 20 This is correct.
E. 16a + 5 + 4 = 16a + 9 <u>This is not correct.</u>
