Answer:
Step-by-step explanation: Using a right triangle as a base, we can assume the length of the bottom is 168 at the start, adding 4 feet to the base length makes it 172, and lowers the height to 47.9 using Pythagorean therom, a^2 + b^2 = c^2

Answer:
40
Step-by-step explanation:
The given shape is made up of 4 equal right angled triangles.
Formula : -
Area of right angled triangle
= bh / 2
Here,
Base ( b ) = 5
Height ( h ) = 4
Area of each right angled triangle
= bh / 2
= ( 5 x 4 ) / 2
[ 4 = 2 x 2 ]
= ( 5 x 2 x 2 ) / 2
= 5 x 2
= 10
Area of 4 right angled triangles
= 4 x 10
= 40
Note : -
" □ " signify " right angle ".
the sides, based on the tickmarks on the picture, are all equal, so the figure is namely a rhombus with four congruent triangles, in this case each of the four triangles have a base of 4 and a height of 4, so
[tex]\stackrel{\textit{area of the four congruent triangles}}{4\left[ \cfrac{1}{2}(5)(4) \right]\implies 40}[/tex]

Can someone help me solve these pls?
Answer:
Question 1. [tex]y=5[/tex]
Question 2. [tex]y=4[/tex]
Step-by-step explanation:
1. [tex]y^{3} =125[/tex]
Take the cube root of both sides:
[tex]{y}=\sqrt[3]{125} \\[/tex]
or
[tex]y=125^{\frac{1}{3} }[/tex]
[tex]y=5[/tex]
2. [tex]y^{2}+4=20\\[/tex]
Subtract 4 from both sides.
Then you have:
[tex]y^{2} =16[/tex]
Take the square root of both sides:
[tex]y=\sqrt{16}[/tex]
[tex]y=4[/tex]
