Answer: C 41 degrees
Step-by-step explanation:
Answer/Step-by-step explanation:
5. ✔️Exterior angle = angle outside the triangle = W
✔️Remote interior angle of the triangle to the exterior angle W = opposite angles to angle W which are X and Y
✔️m<X + m<Y = m<W (exterior angle theorem of a triangle)
✔️m<W + m<Z = 180° (linear pair/angles on a straight line)
6. m<6 = 115°
m<5 = 120°
✔️m<2 = 180° - m<5° (linear pair/angles on a straight line)
m<2 = 180° - 120°
m<2 = 60°
✔️m<3 = 180° - m<6° (linear pair/angles on a straight line)
m<3 = 180° - 115°
m<3 = 65°
✔️m<1 = 180° - (m<2 + m<3) (sum of triangle theorem)
m<1 = 180° - (60° + 65°)
m<1 = 55°
✔️m<4 = 180° - m<1 (linear pair/angles on a straight line)
m<4 = 180° - 55°
m<4 = 125°
Answer:
I would say C
Step-by-step explanation:
Since two negatives make a positive
93. Perimeter of the trapezoid= 5+15+5+9=34 cm
Trapezoid of the trapezoid= 1/2(a+b)h=1/2(15+9)4=48 cm²
94. Perimeter=3+2+4+5+6=20 cm
Divide the figure into 2 small rectangles
Area of the first rectangle=3×2= 6 cm²
Area of the second rectangle=4×5=20 cm²
Area=20+6=26cm²
