To solve this problem you must apply the proccedure shown below. You have that:
1+cot^2θ=csc^2θ (You have that cos^2θ+sin^2θ=1)<span>
1+(cos^2</span>θ/sin^2θ)=csc^2θ
1+(1-sin^2θ/sin^2θ)csc^2θ
sin^2θ+1-sin^2θ=csc^2θ
1/sin^2=csc^2 (You have that 1/sin=csc)
Answer:
18 bulbs for $54
Step-by-step explanation:
if we get 6 bulbs for $18
we can keep going
12 bulbs for $36
18 bulbs for $54
or we can divide 54 by 18 and get 3
then we multiply 3 by 6 and get 18 bulbs :)
if im correct may i please get brainliest
let 2nd angle = x
then 1st angle = 2x-15
then you have 90 = x + 2x-15
2x +x = 3x
so now 90 = 3x-15
add 15 to each side
105=3x
x = 105/3 = 35
1st angle = 35 degrees
2nd angle = 2(35) - 15 = 70-15 = 65
