A.)
3×4=12; 12×4= 48; 48×2= 96; 96+1= 97
B.)
3×4=12; 12+4=16; 16×2= 32; 32+3=35
C.)
3×4=12; 12+4=16; 16×2= 32; 32+1=33
The answer is B
Radius is 3.5
diameter is 7
Answer:
y=15
Step-by-step explanation:
Answer:
a. 15/2 or 7.5 sqcm
b. 20 sqcm
Step-by-step explanation:
Area of a triangle is (base × height)/2.
A = (5×3)/2
A = 15/2 = 7.5cm^2
The area of a parallelogram is just base × height, but yoy have to choose wisely what is the base and height. These two measurements must be perpendicular. So the 4 and 5 are perpendicular. We won't use the measurement 6cm at all.
Area = 4×5
Area = 20 sqcm
Step-by-step explanation:
x+100°=180°{being straight angle}
x=180-100
x=80°
again,
45°+x+y=180°{sum of angle of triangle}
45+80+y=180
y=180-125°
y=55°
hope it helps.
