Answer:
x =21
Step-by-step explanation:
So we know that:
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
Now, solve for x. Add 30 to both sides. The left side cancels:
Now, subtract 2x from both sides. The right cancels:
Thus, the value of x is 21.
First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps
Answer:
the plans can go 560 miles per hour and in 10 hours it can travel 5600 miles
Step-by-step explanation:
1st divide miles over hour so you have to do 3360/6 and the solution you get for that equation is how far the plane can go in miles per hour 2nd for the second question you have to multiply your unit rate by the 10 hours so since our unit rate was 560 miles per hour you would multiply 360 and 10.
A. Factor 28 + 7g 7(g <span>+ 4)
add
28 </span><span>+ 7g
= 7 (g </span>+ 4)
B. (12r + 15) – 65 Remove parentheses
12r+15-65
= 12r - 50
C. 24 – (8p – 12)
24 - (8p - 12) = -8p + 36
24 - (8p - 12) -(8p - 12) 8p + 12
= 24-8p+12
Simplify 24-8p+12
Group like terms
-8p+12+24
Add the numbers 12+24=36
Answer is -8p+36
We need to use Law of sine.
sin A/a = sin C/c
sin A/|CB| = sin C/|AB|
sin A/14 = sin(118⁰)/ 20
sin A = (14*sin(118⁰))/ 20
A=arcsin((14*sin(118⁰))/ 20) ≈ 38⁰
