Answer:
x = 12
Step-by-step explanation:
the two equations shown should add up to 180. so I did this equation: (10x-20)+ (6x+8) = 180 and I solved for x
Answer:
1ST GRAPH
Step-by-step explanation:
1st GRAPH
Because the equation is trying to express:
<u>p is bigger or equal to -1</u>
and in graph no.1 the inequality is at -1 and everything after it could be p. As P is bigger than -1
Answer: The missing angle is 13°
Step-by-step explanation:
Let ∠B
be the missing angle.
Let ∠A
be the angle that measures
77∘Let ∠C
the right angle that measures
90∘
The following is true of all triangles:
∠A+∠B+∠C=180∘
Express the above equation as
∠B
in terms of the other angles:
∠B=180∘−∠A−∠C
Substitute the values for ∠A and ∠C
∠B=180∘−77∘−90∘
∠B=13∘
