Answer:
Step-by-step explanation:
58+q=180 (opposite angles of a cyclic quadrilateral are supplementary)
q=180-58=122°
similarly p+90=180
p=180-90=90°
Answer:
Step-by-step explanation:
Equation: 
1). 
2).
For First Question:
As, we find the value of x for parallel condition of line a and b
so, m∠3 = m∠1 and m∠2 = 180°-m∠1 = 180°-(2x+15)° [ As straight line contain total 180°]
Now,
m∠2 = <span>m∠6 [ Because they are corresponding angles]
180</span>-(2x+15)=(3x+10)
180=3x+10+2x+15
x= 31 satisfies the condition of a||b
For second Question:
As, it is issoceles triangle So side AC = side BC So, m∠A=<span>m∠B
</span>4x+5=5x-1
x=6
So,
m∠A=29° and triangle contain total 180°
<span>m∠C=180-29-29
</span> =122°
Option D is correct
Answer
8
Step-by-step explanation:
104 - 8, and then divide 96 by 12 equals 8
