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: 380
Step-by-step explanation: Create an equation, so if 65% waved then 35% of the total (x) didn't wave, which are 133 people, so .35x=133, solve for x so x=133/.35 so x=380
Yes,because 4* 8=36 slices and so 6*6=36 total.
Answer:
(-3,3)
Step-by-step explanation:
4-7 is -3 and 1+2 is 3 so it is (-3,3)
Answer:
1st picture (tri) = 16y+8
2nd picture (tri) = 12x-9
3rd picture (sq) = 21x+35
Step-by-step explanation:
Triangle area = (Base x Height) divided by 2
#1.) 16(2y+1) = 32y + 16 (32y+16)/2 = 16y+8
