Answer:
Step-by-step explanation:
Isolate the variable and divide by the coefficient to solve for a variable.
Answer2.0
Step-by-step explanation:
Answer:
a = 1/4
Step-by-step explanation:
To solve for a, you need to isolate it by dividing both sides by 28.
7/28 = 1/4
a = 1/4
Check your answer by plugging x = 1/4 back into the equation.
28(1/4) = 7
7 = 7
Your answer is correct.
Hope this helps!
Angles LNM and MNI are supplementary, so their measures sum to 180°. This means
∡ LNM + ∡ MNI = 180°
∡ LNM = 180° - (19<em>x</em> + 2)°
The sum of the interior angles of any triangle is also 180°, so
∡ LNM + ∡ NML + ∡ MLN = 180°
(180° - (19<em>x</em> + 2))° + (15<em>x</em> - 2)° + (6<em>x</em>)° = 180°
Solve for <em>x</em> (I'll omit the degree symbol):
180 - 19<em>x</em> - 2 + 15<em>x</em> - 2 + 6<em>x</em> = 180
2<em>x</em> - 4 = 0
2<em>x</em> = 4
<em>x</em> = 2
Then ∡ MNI = (15•2 - 12)° = (30 - 12)° = 18°.
