Two angles are supplementary. The measure of the first angle is 10 degrees more than three times the second angle. Find the measure of each angle

Answers

Answer 1

Answer:

Answer:

137.5° and 42.5°

Step-by-step explanation:

supplementary angles are two angles whose sum is equal to 180°.

Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.

we know that the sum of first and second angles is 180° (supplementary angles)

so, (3(x)+10°)+(x) = 180°

4(x) = 170°

x = 170°/4 = 42.5°

so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°

therefore, the angles are 137.5° and 42.5°.

A number increased by 4 is the same as 19 minus 2 times the number

Answers

Here :

x+4=19-2x
x+2x=19-4
3x=15/3
x=5

So it says A NUMBER We don't know what number SO we are gonna add any variable you want.
LET SAYS m = NUMBER INCREASED
is means equal
m+4= 19-2m

m+2m=19-4
3m=19-4
3m=15
3÷3m=15÷3 3and 3 cancel each other and 15÷3 is 5
m=5

Team one had twice as many workers as team two. The number of workers in team one is reduced by 5 and the number of workers in team two is reduced by 2. How many workers are there in each team now if there are 7 more workers in team one?

Answers

The Team 1 now has 15 members and Team 2 now has 8 members.

We have given that team one had twice as many workers as team two.

Let us consider,x workers in team one initially

y workers in team two initially.

we know that

$x=2y.... 1$

Now next

$(x-5)=(y-2)+7\n x-5= y+5\nx=y+10.........2$

We have to solve this equation by using substitution method

What is the substitution method for linear equation?

The substitution method functions by substituting the one y-value with the other.

Use the value of 1 in equation 2 we get

$2y=y+10\n 2y-y=10y=10x=2*10\n x=20$

Therefore we have,

Team 1 now has 20-5 = 15 members

Team 2 now has 10-2 = 8 members

let

x-------> workers in team one initially

y-------> workers in team two initially

we know that

x=2y-----> equation 1

(x-5)=(y-2)+7-----> x-5= y+5----> x=y+10---------> equation 2

equate equation 1 and equation 2

2y=y+10-----> y=10

x=2*10------> x=20

Team 1 now has 20-5 = 15 members
Team 2 now hase 10-2 = 8 members
