Let x = the unknown angle
sine of an angle is measure of the opposite leg divided by the hypotenuse.
sin x = 10/21
To now solve for x, we so the inverse of sine.
sin⁻¹(10/21) = x
Plug this into your calculator.
x ≈ 28.44 degrees. This would round down to 28 degrees, option B is your answer.
Answer:
multiples of 2 2,4,6,8,10,12,14,16,18,20
multiples of 3 3,6,9,12,15,,18,21,24,27,30
Step-by-step explanation:
Lcm is 6
Answer:
the answer its 44=0
Step-by-step explanation:
18y-6y+22=11(y-2)+y1
We move all terms to the left:
18y-6y+22-(11(y-2)+y1)=0
We add all the numbers together, and all the variables
12y-(11(y-2)+y1)+22=0
We calculate terms in parentheses: -(11(y-2)+y1), so:
11(y-2)+y1
We add all the numbers together, and all the variables
y+11(y-2)
We multiply parentheses
y+11y-22
We add all the numbers together, and all the variables
12y-22
Back to the equation:
-(12y-22)
We get rid of parentheses
12y-12y+22+22=0
We add all the numbers together, and all the variables
44=0
are not solution for this equation
Hope helps you and have a great day !
Answer:
A
Step-by-step explanation:
both equation is y so
2x - 5 = x² - 5
2x = x²
0 = x² - 2x
0 = x(x-2)
x = 0
x = 2
for x = 0
y = 2x - 5
y = 0 - 5
y = -5
(0,-5)
for x = 2
y = 2x - 5
y = 2(2) - 5
y = -1
(2,-1)
