Answer:
∠C° = 138°.
Step-by-step explanation:
Given : Figure.
To find : Which is the measure of angle C
Solution :We have given that
We can see from the given figure angle C and angle 45 are formed on a line.
So, it formed linear pair angle
According to property : Sum of linear pair angle is 180 degree.
Then ,
∠42° + ∠C° = 180°.
On subtracting both sides by 42.
∠C° = 180 -42.
∠C° = 138°.
Therefore, ∠C° = 138°.
Answer:
x = - 7, x = 0
Step-by-step explanation:
Given
x² + 7x = 0 ← factor out x from each term on the left side
x(x + 7) = 0
Equate each factor to zero and solve for x
x = 0
x + 7 = 0 ⇒ x = - 7
