The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
The answer is (4,-20)

Answer:
x = 91.5
Step-by-step explanation:
for 30.5 miles travelled gas used is 1 gallon ← unit rate
To calculate distance travelled multiply gas used by 30.5
For 3 gallons used
distance travelled = 3 × 30.5 = 91.5 miles
⇒ x = 91.5
Your answer should be xy.
