Answer:
A = 148 cm^2
Step-by-step explanation:
To calculate the surface area of the cuboid we use the following equation
A = 2 x (lh + lw+ hw) (l: length, w: width, h: height)
A = 2 x (6*5 + 6*4 + 5*4)
A = 2 x (30 + 24 + 20)
A = 2 x 74
A = 148 cm^2
Answer:
(D) he should have found that there are no solutions because the statement is false
Answer:
0.25
Step-by-step explanation:
Answer:
- ∠R = 56°
- ∠Q = 90°
- ∠S = 34°
Step-by-step explanation:
The given triangle is a right angled triangle.
So, the angles in the triangle are :
- 90°
- (2x + 38)°
- (5x - 11)°
Solving according to <u>angle sum property</u>,
Sum of all angles in a triangle is 180°
90° + (2x + 38)° + (5x - 11)° = 180°
117° + 7x = 180°
7x = 180° - 117°
7x = 63°
x = 9
Angles =
2(9) + 38
56°
5(9) - 11
34°
- ∠R = 56°
- ∠Q = 90°
- ∠S = 34°
The angles are 56°, 90° and 34°.
