The smallest angle of a triangle is measure x degrees. The second angle is 45 degrees more than the smallest angle. The third an
gle is three times larger as the smallest angle. Write algebraic expression to express measures of the second and third angles of the triangle.
1 answer:
Answer:
Step-by-step explanation:
The sum of the angles is 180°
x+(x+45)+(3x) = 180
5x = 135
First angle = x = 27°
Second angle = x+45 = 72°
Third angle = 3x = 81°

<span>Let n = the number of pages not read
Then the number of pages read = n/4 + 3
Since the total number of pages is 193, we have
n + n/4 + 3 = 193
5n/4 = 190
n = 152
At 8 pages per day it will take 152 pages/ 8 pages/day = 19 days
