Answer:
m∠A = 120°
m∠C = 45°
Step-by-step explanation:
all triangle angles add up to 180
(12x + 12) + 15 + (3x +18) = 180
15x + 45 = 180
15x = 135
x = 9
m∠A = (12x + 12) = 12(9) + 12 = 120
m∠C = (3x +18) = 3(9) + 18 = 45
The slope of the line is: -3/2
Answer:
The length of the width is 1
Step-by-step explanation:
Since we are not finding the hypotenuse and we are given it, we have to rearrange the a² + b² = c² equation because that equation is to find the hypotenuse of a right - angled triangle and we are not asked to find the hypotenuse but the width so
a² + b² = c²
→ Substitute in the values
( √3 )² + b² = 2²
→ Simplify equation
3 + b² = 4
→ Minus 3 from both sides to isolate b²
b² = 1
→ Square root both sides to isolate b
b = 1
