If you use division you will find 30ft divided by the 7.5ft is 4ft so 7.5ft*4ft=30ft squared
I wonder what shape the window is? It has a radius so I expect a circle but you use the word perimeter which is usually reserved for shapes with sides.
So my guess is you are looking for the circumference of a circular window with radius 20. The circumference is given by (pi)d where d is the diameter. The diameter is twice the radius so 40. We use 3.14 to approximate pi.
That makes the circumference (the distance around the circle) = (40)(3.14)=125.6
Answer:
See explanation
Step-by-step explanation:
Consider triangles ABC and ACD. These triangles are right triangles because
In these triangles:
- - given
- by reflexive property of equality
So,
- by HA theorem.
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
The formula for the volume of a cylinder is π × radius^2 × height. The π and height will remain the same, so the only difference will be in the radius. 6^2 = 36, and 3^2 = 9, so 9 is 1/4 of 36 (36 ÷ 4 = 9) which means that the answer is 1/4. I hope this helps!
Answer:
x=5
Step-by-step explanation:
First you have to solve for y. Since it is a isoceles triangle, the two base angles are equal. You dont even need to solve for y because both of them will equal 73. Now you know two of the angles are 73 degrees, 146 in total. Since you know the total degrees in a triangle is 180, set up an equation that is adding all the angles to equal 180. Then solve for x.
Solve:
73+73+(6x+4)=180
146+6x+4=180
150+6x=180
6x=30
x=5
