Answer:
m∠A = 15°; m∠B = 89°; m∠C = 76°
Step-by-step explanation:
The sum of the three interior angles of a triangle is 180°.
Let x = m∠A
Then 3x + 44 = m∠B
and x + 61 = m∠C
x + 3x + 44 + x + 61 = 180
5x + 105 = 180
5x = 75
x = 15
m∠A = 15°
m∠B = 3(15) + 44 = 45 + 44 = 89°
m∠C = 15 + 61 = <u> 76°</u>
Sum = 180°
Answer:
34cm²
Step-by-step explanation:
Find diagram in the attached file.
Since each square on the grid represent 1cm², the length of the each square will be 1cm
Area of the irregular shape can be gotten by breaking the irregular shape into three shapes which are the triangle, rectangle and a parallelogram.
Area of the irregular shape = area of triangle + area of rectangle + area of parallelogram
For TRIANGLE
Area of triangle = 1/2×base×height
Since the base of triangle is on 4square grid,
Base = 4cm
Height = 2cm
Area = 1/2×4×2
Area of ∆ = 4cm²
FOR RECTANGLE
Area of rectangle = Length ×Breadth
Length = 3cm
Breadth = 5cm
Area of the rectangular shape = 3×5
= 15cm²
FOR PARALLELOGRAM
Area of a parallelogram = Base × Height
Base = 5cm
Height = 3cm
Area = 5cm×3cm
Area = 15cm²
Area of the irregular shape = 4cm²+15cm²+15cm²
=34cm²
Let
x--------------> the complete figure
we know that
the figure is divided into 6 equal parts
x= (x/6)+(x/6)+(x/6)+(x/6)+(x/6)+(x/6)
red=(x/6)+(x/6)--------> red=(2x/6)=x/3
blue=(x/6)+(x/6)+(x/6)+(x/6)=(4x/6)=2x/3
Rashad say that 2/4 of the figure is red-------> Rashad is wrong
because (2/4) <span>It is half of the figure
</span>the correct thing is to say (1/3) o the figure is red and (2/3) of the figure is blue
