Someone thats good at geometry please help asap!
frosja888 [35]

Answer:

x=125

Step-by-step explanation:

∠PAT=180° - ∠ATP - ∠APT

∠PAT=180 - 3x - 3 -4x -4= (173 - 7x)°

3x + 3 + 4x + 4 + 173-7x = 180  

⇔x = 125

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Well the area of a trapezoid is defined by the following formula:
A = \frac{1}{2}(b_{1} + b_{2})h where b₁ and b₂ are the bases of the trapezoid and h is the height of the trapezoid.

Let's plug in what we know into this formula:
h = 7  the perpendicular distance between the two bases
b₁ = 15  the shorter parallel side
b₂ = 25  the longer parallel side made up of 4 + 15 + 6
so, A = \frac{1}{2} (15+25)(7)=140

This is in square units of measure of course, so 140 in²

What is the volume of a cube with a side length of 3t^5units?<br>Cube V = s^3​
balandron [24]

Answer:

V=27t^{15}\ units^3

Step-by-step explanation:

we know that

The volume of a cube is equal to

V=s^{3}

where

s is the side length of the cube

we have

s=3t^5\ units

substitute in the formula

V=(3t^5)^{3}

V=(3^3)(t^5)^{3}

Remember the power rule

(a^m)^n=a^{m*n} ----> multiply the exponents

so

V=(3^3)(t^{5*3})=27t^{15}\ units^3
