Answer:
Step-by-step explanation:
Both legs are equal, which implies the triangle is a 45-45-90.
The hypotenuse of this triangle is:
Answer:
A. The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.
Step-by-step explanation:
Given

Efficient way of solving the equations
<em>The efficient way of solving this problem is by solving for x in the first equation because it has a coefficient of 1;</em>
The evidence is shown as follows;
<em>Make x the subject of formula in equation 1</em>
<em>Substitute 1 + 3y for x in equation 2</em>
<em>Open bracket</em>
<em>Make y the subject of formula</em>
<em>Divide both sides by 23</em>
Recall that x = 1 + 3y
<em>Substitute 0 for y in the above expression</em>
Solving for y in the second equation will take more steps
X = 3; B = 70
60 + 15x + 5 + 22x + 4 = 180
69° + 37x = 180
37x = 180° - 69°
37x = 111°
x = 111/37
x = 3
B = 22x + 4
B = 22(3) + 4
B = 66 + 4
B = 70
Step-by-step explanation:
okay so that's an inequality. You solve it the same way you saw the regular equation. the only difference is that if you divide or multiply by a negative number then you have to turn the sign around.
