Answer:
0.6820
Step-by-step explanation:
Given data
Angle= 47°
Hence we want to find
cos 47°
From calculator
cos 47°=0.681998
to 4 dp
0.6820
In similar figures, the ratio between corresponding sides are the same.
![\frac{25}{35}=\frac{35}{49}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B35%7D%3D%5Cfrac%7B35%7D%7B49%7D)
Simplify the two to see that they are equal.
The top and bottom of the left fraction are divisible by 5.
The top and bottom of the right fraction are divisible by 7.
![\frac{5}7=\frac{5}7](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D7%3D%5Cfrac%7B5%7D7)
Of course, the dimensions of that third picture would have to be this fraction.
Let's test these answers.
![\frac{5}6\neq\frac{5}7](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D6%5Cneq%5Cfrac%7B5%7D7)
⇒ A is not a solution
![\frac{30}{42}=\frac{5}7](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B42%7D%3D%5Cfrac%7B5%7D7)
⇒
B is the solution
(divide the top and bottom by 6)
The <span> answer is 6.75. Since if you divide the number by 8 you get 6.75.</span>

140 + 775 = 915
Answer:
C. (4,28)
Step-by-step explanation:
When y = 8x - 4 ; x = 4
when u substitute x in the equation
the value of y = 28
y = (8 x 4) - 4
= 32 - 4
= <u>2</u><u>8</u><u>.</u>
As coordinates it would be (x,y) = <u>( 4,28 )</u>
