Adjacent angles
Step-by-step explanation:
Adjacent = next to / side by side
X and y
x:y=3:5
or
x/y=3/5
when 4 is subtracted from x and 8 is added to y new ratio is 2:7
(x-4)/(y+8)=2/7
we have
x/y=3/5
(x-4)/(y+8)=2/7
get rid o frationc
x/y=3/5
times both sides by 5y
5x=3y
(x-4)/(y+8)=2/7
times both sides by 7(y+8)
7(x-4)=2(y+8)
7x-28=2y+16
add 28 both sides
7x=44+2y
we have
5x=3y
and
7x=2y+44
multiply first equation by 2 and seecond equaiton by 3
10x=6y and 21x=6y+132
sub 10x for 6y
21x=10x+132
minus 10x both sides
11x=132
divide both sides by 11
x=12
x/y=3/5
12/y=3/5
times both sides by 5y
60=3y
divide both sid esyb 3
20=y
12 and 20
the greater is 20
Answer: x is 36 degrees
Step-by-step explanation:
To solve this triangle, we can use sin -1 x = 14 / 24. This gives us 35.69 degrees, but in your answer choices you only get integers. We can round this up to 36 degrees to get the answer.
Answer:
<h2>x = 10.3</h2>
Step-by-step explanation:
Use sine.
We have:
<em>look at the table in the picture</em>
Substitute:
<em>multiply both sides by 16</em>
