Answer:
32
Step-by-step explanation:
angel A= AngelC ( due to isosceles triangle)
now,
angel A+ Angel B + Angel C = 180° ( sum of the three angles of triangle is 180°)
74°+angle B+ 74° = 180°
148° + Angel B = 180°
angel B = 180° - 148°
therefore, Angel B = 32
Answer:
c= 20h + 60
Step-by-step explanation:
The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.
Answer:
15°
Step-by-step explanation:
All angles in an equilateral triangle are equal.
Angle sum property of triangle = 180°
<1 + <2 + <3 = 180°
<1 = <2 = <3 = 60°
4y = 60
y = 60/4
y = 15°
