Answer:
y=7/20
Step-by-step explanation:
7y*38=93
divide 38 on both sides this cancels out the 38 on the left side
this gives you
2.45
then divide 7 from both sides.
this gives you roughly 7/20
Multiply both sides by x so that x will be in the numerator
<u>Answer:</u>
An obtuse triangle has two angles 45 and 18. The value of the unknown angle is 
<u>Solution:</u>
Given that two angles of an obtuse triangle is 45 and 18.
Third angle is θ
We are asked to find the value of third unknown angle theta
According to <em>angle sum property of triangle</em>, sum of three angles of triangle is 
This means in our case sum of 45, 18 and θ should be 

Hence value of unknown third angle of an obtuse triangle is
The answer is 54.27. Hope I was halpful
