Hey there! :)
You have to find the area of all of them and add it together.
Formulas:
Area of a square: l · w
Area of a triangle: (b · h) ÷ 2
Square -
l = 3
w = 3
3 × 3 = 9
Triangle -
b = 3
h = 3
(3 × 3) ÷ 2
9 ÷ 2 = 4.5
There are 4 triangles
4.5 × 4 = 18
9 + 18 = 27
The surface area ⇒ 27 cm²
Answer:
C. Use a straightedge to measure the length of the line segment.
Step-by-step explanation:
Two or more lines are said to be congruent when they are approximately equal in length to each other. Construction of congruent line segments involves some steps. And these steps require the use of appropriate constructing instruments and materials.
The given question gives options from which one is a correct step for constructing congruent line segments. The appropriate step from the options given is C. A straightedge can be used to measure the length of the line segment.
Answer:
-8, 2.8, -3.35, -8 1/2
Step-by-step explanation:
Let the sons age be x years then
- the fathers age is 2x + 5 years, So:-
2x + 5 - x = 25
x = 25 - 5 = 20
The father is 2 (20) + 5 = 45 years answer
Step-by-step explanation:
perp. -1/2
y + 3 = -1/2(x - 4)
y + 3 = -1/2x + 2
y = -1/2x - 1
