Answer:
m∠1 = 60°
m∠2 = m∠4 = 39°
m∠3 = m∠5 = 21°
Step-by-step explanation:
ΔWXY is a equilateral angle,
Therefore, all angles of the the triangle are equal in measure.
m∠W + m∠X + m∠Y = 180°
3m∠W = 180°
m∠W = 60°
Since, ΔWZY is an isosceles triangle,
m∠3 = m∠5
m∠3 + m∠Z + m∠5 = 180°
m∠3 + 138° + m∠3 = 180°
2m∠3 = 180 - 138
m∠3 = 21°
Therefore, m∠3 = m∠5 = 21°
Since, m∠2 + m∠3 = 60°
m∠2 = 60 - 21
= 39°
Since, m∠4 + m∠5 = 60°
m∠4 = 60 - 21
= 39°
m∠1 = 60°
Answer:
Option "A" is correct
Step-by-step explanation:
P(A) probability of event A is true
P(B) probability of event B is true
P(AB) probability of event AB is true
P(BA) probability of event BA is true
P(AB)= (BA) × (A)/(B)
Answer:
t = 26
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
Step 2: Check if solution is correct.
Therefore, t = 26.
Answer:
r = 5
Step-by-step explanation:
r³ = 125
r × r × r = 125
5 × 5 × 5 = 125
25 × 5 = 125
125 = 125
