Answer:x=5/3 y=14/3
Step-by-step explanation:
y=4x-2...........(1)
y=x+3..............(11)
Subtract (11) from (1)
0=3x-5
Collect like terms
3x=5
Divide both sides by 3
3x/3=5/3
x=5/3
Substitute x=5/3 in y=x+3
y=5/3 + 3
y=(5+9)/3
y=14/3
Therefore x=5/3 y=14/3

Angle B:</span>
_______________________________________________________
Given: m∡A = 99° ;
∡A and ∡B are "supplementary angles" ;
and supplementary angles add up to 180°.
_______________________________________________________
<span> → So, m∡B = 180 − 99 = 81° </span>.

Angle C: 99° .
_______________________________________________________
Explanation:
_______________________________________________________
Given: m∡A = 99° .
∡A and ∡C are "vertical angles". Vertical angles are congruent.
______________________________________________________
→ So m∡A = m∡C = 99° .
______________________________________________________
Angle D: 81° .
______________________________________________________
Explanation:
______________________________________________________
∡B and ∡D are vertical angles. Vertical angles are congruent.
As previously determined above, m∡B = 81° .
______________________________________________________
→ So, m∡D = m∡B = 81° .

To find the percentage of 28 from 70:
28/70=0.4
0.4=40%
Answer:
Step-by-step explanation:
To find them you need to plug them in to solve and then eliminate the following by the pass through method. This can help bring the final answer to the "table" leaving you with the final measure of each described angle.
