Because of the transversal and the parallel lines, we know that A+B=180°.
So:
5x + 20 + 9x - 92 = 180
14x - 72 = 180
14x = 180 + 72
14x = 252
x = 252/14
x = 18
A = 5x + 20
A = 5*18 + 20
A = 90 + 20 = 110
(Let’s check:
B = 9*18 - 92
B = 162 - 92
B = 70
70 + 110 = 180)
Answer:
Step-by-step explanation: 1/2x=16
16x4=64, Although this is not exactly 55 cookies, you can either make more or less. So you need 4 salt, to make 55.
I cant see anything sorry
For this problem, we use our knowledge on trigonometric functions on a right triangle to be able to calculate for the x and y components of the walk. We do as follows:
sin 60 = ax / 9.4
ax = 8.14
cos 60 = ay / 9.4
ay = 4.7
Answer:
this angle is a right angle(90°)
and one of the 2 angles is 30
3x+30=90
3x=90-30
3x=60
x=20
==> B
