The value of x is 13°.
Solution:
<em>In triangle, sum of all the interior angles = 180°</em>
m∠A + m∠B + m∠C = 180°
(3x)° + (4x – 1)° + 90° = 180°
3x° + 4x° – 1° + 90° = 180°
7x° + 89° = 180°
Subtract 89° from both sides of the equation, we get
7x° = 91°
Divide by 7 from both sides of the equation, we get
x° = 13°
The value of x is 13°.
"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that
a = kb
We're given that a = 18 and b = 3, so that
18 = 3k ⇒ k = 6
Then when b = 5, we would have
a = 6 × 5 = 30
Answer:
8/15
Step-by-step explanation:
Add: 1/5
+ 1/3
= 1 · 3/
5 · 3
+ 1 · 5/
3 · 5
= 3/15
+ 5/15
= 3 + 5/15
= 8/15
