Answer:
B
Step-by-step explanation:
Since the triangle is isosceles the base angles are equal
One base angle is given as 70°, thus the other base angle is also 70°
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180 for third angle
third angle = 180° - (70 + 70)° = 180° - 140° = 40° → B

Answer:
x=40 and y= 60
Step-by-step explanation:
step:1
Let 'x' and 'y' are two numbers
given data the sum of two numbers is 100
x+y = 100......(1)
Given difference of two numbers are
x - y = -20 ......(2)
Step :2
solving the equation (1) and (2)
adding the equations (1) and (2)
x+y+x-y=100-20
cancelling 'y' terms are
2 x = 80
dividing "2" on both sides, we get
x = 40
Step :3
substitute x = 40 in equation (1)
x + y =100
40 + y = 100
subtracting "40" on both sides, we get
40 + y - 40 = 100 -40
y = 60
Final answer:-
The two numbers are x = 40 and y= 60

The percentage is the indicating hundredth thus 903 is 43% of 2100.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Suppose 903 is 43% of the number x.
Since, any percentage of a number is the hundredth value thus,
43% of x = (43/100)x
(43/100)x = 903
x = 903 x 100/43
x = 2100
Hence "The percentage is the indicating hundredth thus 903 is 43% of 2100".

Answer:
2100
Step-by-step explanation:
43% can be represented as 0.43
%43 of a number equals 903 basically means, x * 0.43 = 903 , you can divide both sides by 0.43 and you will get a result like this x = 903 / 0.43, x = 2100

all form a right triangle. Please sketch a picture of the set-up
on your scratch paper.
In a right triangle,
(the side adjacent to one of the acute angles)
divided by
( the hypotenuse)
is the cosine of the angle.
In this problem ...
-- the acute angle in the triangle is 67°
-- the distance along the ground is the side adjacent to the angle ... 137-ft.
-- the wire is the hypotenuse of the triangle.
-- so, cosine(67°) = (137-ft) / (length of the wire)
Multiply each side by
(length of the wire) : cosine(67°) x (length of the wire) = (137-ft)
Divide each side
by cosine(67°) length of the wire = (137-ft) / cosine(67°)
Look up cosine(67°)
on your calculator: length of the wire = (137-ft) / (0.390731)
= 350.624 .
rounded to two decimal places: 350.62 ft

Here are the steps involved in answering this question:
1. Write 52 out of 50 as a fraction which is
2. Turn the fraction into a decimal. To do this, divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.
3. You get 1.04. Now, turn this into a percent. Move the decimal, 2 places to the right or just multiply the decimal by 100.
1.04 = 104%
The final answer is 104%.
Another way of doing this is to get 100 as a denominator.
Since, percent means, "Out of 100", we have to make the denominator 100.
1.
Just multiply each side by 2.
Again, the final answer is, 104%
