Answer:
Surface Area = 84.8 cm²
Step-by-step explanation:
This wedge is simply a triangular prism.
We are given;
Height of door wedge; H = 5 cm
Height of triangular base;h = 3.7 cm
Congruent sides; S2 = S3 = 5cm
base of triangular side;b = S1 = 4 cm
Now, formula for surface area of triangular prism is;
SA = bh + (s1 + s2 + s3)H
Thus, plugging in the relevant values, we have;
SA = (4 x 3.7) + (4 + 5 + 5)5
SA = 14.8 + 70
SA = 84.8 cm²

Step-by-step explanation:
24 / (4 x 2 - 5)
PEMDAS
P: Parenthesis = (4 x 2 - 5)
E: Exponents: None
M: Multiplication = (4 x 2 - 5) = (8 - 5)
D: Division = Not yet, because the Parenthesis is not done.
A: Adding = None
S: Subtracting = (8 - 5) = 3
Divide = 24/3 = 8
Answer:
8.3units
Step-by-step explanation:
formula 2πr × x/360
where x= angle of sector
therefore
2× 22/7 × 14 × 34/360 = 8.3
