Answer:
70.8 to one decimal place,
or to be exact : 70.7873
Step-by-step explanation:
In right angle triangles, trigonometry functions can be used
here tan out of sin, cos ,tan seems the most appropriate
tan(x) = opposite/adjacent
tan(x) = 6.6/2.3
x = tan^-1 (6.6/2.3)
x = 70.7873
I only know 23
6x-4 x=4-6=-10
4x+24 x=24-4=20
So! 20-(-10)=10 or 30 because you change the sign with this rule
if the sign are the same you keep change, change. which means keep 20 change - to + and change - to +, so then it becomes 20+(+10)
Answer:
B. The ratio of the area of the scale drawing to the area of the painting is 1:16
C. The ratio of the perimeter of the scale drawing to the perimeter of the painting is 1:4
Step-by-step explanation:
The ratio of the area of similar figures/shapes = the square of the ratio of any of their side lengths
Since the scale drawing of the rectangular painting and the actual rectangular painting are similar, therefore,
The ratio of the area of the scale drawing to the painting = 1²:4²
= 1:16
Also, comparing the ratio of the perimeter of the scale drawing to the perimeter of the painting will be the same as the scale factor = 1:4
