Answer: x=37.8, you can solve by writing a proportion
Angles 1 and 2 are supplementary angels because they form a line.
Angles 1 and 2 are adjacent angles because they share an interior ray and they have a common vertex.
We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?
We can set up the proportion as :
width 1 : length 1 = width 2 : length 2
20 : 30 = 5 : x
We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)
20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm
Answer:
11/4
Step-by-step explanation:
2 times 4 equals 8 and plus 3 equals 11 and dem is 4 so 11/4
Answer:
C
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanC = 
= 
= 
, then
C = 
( )
