Answer:
x = 13.5
Step-by-step explanation:
We know that base angles of an isosceles triangle are equal. The base angles of the triangle are (4x)° each. The vertex angle of the traingle is (6x-9)°. So according to angle sum property of triangle,
Answer:
18π
Step-by-step explanation:
You have to multiply the height and the width together and then multiply by pi but since it is in terms of pi it is 18π
Answer:
We have:
7 + 4 = 11;
11 - 7 = 4;
11 x 2 = 22;
4 x 4 = 16;
22 - 16 = 6;
Finally, 8 x 6 = 48;
Step-by-step explanation:
3y+7=31
3y=24 (we subtracted 7 from both sides)
24 divided by 3 is 8
Y=8
Answer:
B is the best answer
The question is illustrated with the attached figure.

Determine XY
To solve for XY, we make use of the tan function, which states that:
tan\theta = \frac{Opposite}{Hypotenuse}tanθ=
Hypotenuse
Opposite
In this case:
tan\ 60= \frac{YZ}{XY}tan 60=
XY
YZ
Substitute 4 for YZ
tan\ 60= \frac{4}{XY}tan 60=
XY
4
Make XY the subject
XY= \frac{4}{tan\ 60}XY=
tan 60
4
tan\ 60 =\sqrt 3tan 60=
3
So, the expression becomes:
XY = \frac{4}{\sqrt 3}XY=

Rationalize:
XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}XY=
