Answer:
I believe it is b
Step-by-step explanation:
M∠ADB + m∠BDC = m∠ADC [<span>angle addition postulate]
x + x + 10 = 60
2x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2
x = 25
a
m</span>∠ADB = x = 25°
b
m∠BDC = x + 10 = 25 + 10 = 35°
Answer:
Step-by-step explanation:
You have two methods to expand this binomial.
Method 1
If you have the expression:
You can write the expression it in the following way:
Then, apply the distributive property:
Simplify the expression:

Method 2
For any expression of the form:
Its expanded form will be:
If
Answer:
D. 89°
Step-by-step explanation:
On the line segment "C," 89 degrees is shown in one corner. x is directly across from it, therefore being the same degrees
