X = 5
The length of an inscribed angle is 1/2 the arc it intercepts so the angle on the bottom twice equals the measure of the arc above.
15x - 3 = 2 (6x + 6)
15x - 3 = 12x + 12
3x = 15
x= 5
Hope this helped

AB = x + 15 DC = 4x AD = x + 10 BC = ? Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent. Show
dexar [7]

Answer:

BC=15\ units

Step-by-step explanation:

we know that

In a parallelogram opposite sides are congruent

In this problem

we have that

AB and DC are opposite sides

AD and BC are opposite sides

so

AB=DC

AD=BC

step 1

Find the value of x

AB=DC

substitute the given values

x+15=4x

solve for x

4x-x=15

3x=15

x=5\ units

step 2

Find the length of AD

we have that

AD=x+10

substitute the value of x

AD=5+10=15\ units

step 3

Find the length of BC

Remember that

AD=BC ----> by opposite sides

therefore

BC=15\ units

How would you write 87 as a Roman numeral?
ddd [48]

Answer:

LXXXVII

Step-by-step explanation:

L=50 X=10 V=5 I=1

So basically you need to figure out what adds up to the 87. so use L, or 50. now XXX=30. so now you have 80 so we still have 7 left over, so we can write 7 I's or a 5, (V) and two I's. We should use the V and the I. So we take one V, or 5. and two I's which together is 7. which leads us too LXXXVII. also always remember to have the biggest number first, in this case the L (50).

30 POINTS!!! Louie is trying to find a rectangular canvas for his art project. Its diagonal must measure 23.3 inches and form a
Lisa [10]

Answer:

12 inches

Step-by-step explanation:

Given

\theta = 31^{\circ}

diagonal = 23.3\ in

Required

Determine the height of the canvas

The question is illustrated using the attached image.

Using the attachment as a point of reference, the height is calculated from

sin \theta = \frac{opp}{hyp}

This gives:

sin 31^{\circ}= \frac{h}{23.3}

Make h the subject

h = 23.3 * sin(31^{\circ)

h = 23.3 * 0.5150\\

h = 11.9995

h = 12\ inches
