Answer:

l and n are parallel

Step-by-step explanation:

360° around a point

65° x 2 = 130

360 - 130 = 230

230/2 = 115

115 ° are corresponding angles

Triangle P R Q is shown. Angle R P Q is 39 degrees. The length of P R is 6, the length of R Q is p, and the length of P Q is 8.
KATRIN_1 [288]

According to law of cosines the length of RQ can be written as p^{2} =6^{2} +8^{2} -2*6*8cos(39).

Given the length PR is 6 , the length of RQ is p, the length of PQ is 8 and the angle RPQ is 39 degrees.

A length of the triangle can be written as according to law of cosines if sides are given and one angle is a^{2} =b^{2} +c^{2} -2bccos(A)

We have to just put the values in the above equation.

as p^{2} =6^{2} +8^{2} -2*6*8cos(39).

p is the side opposite to angle given , the length of other sides are 6 and 8 and angle is 39 degrees.

Hence the side can be written as according to law of cosines if the angle is 39 degrees is  as p^{2} =6^{2} +8^{2} -2*6*8cos(39).

Find the value of k for x^2 - 2kx+7k -12=0 so that they have two equal roots
Alisiya [41]

Step-by-step explanation:

x^2 -2kx +7k -12 = 0

two equal roots -->Δ = b^2 -4ac = 4k^2 - 4(7k-12)=0 = 4(k^2 - 7k +12)=4(k-4)(k-3)=0

so k =3 and k =4

Jordan is putting a fence around a garden that is shaped like a half circle and rectangle
grin007 [14]

Answer:

92 ft  

Step-by-step explanation:

Assume the garden has the shape shown below.

The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.

1. Around the rectangle

Distance = 28 ft + 14 ft + 28 ft = 70 ft

2. Around the semicircle

For a circle.

C = 2πr

For the semicircle,

½C =½(2πr) = πr  

D = 14 ft, so

r =    7 ft

\text{Distance} = \dfrac{22}{7} \times \text{7 ft} = \text{22 ft}

3. Total distance

Distance = 70 ft + 22 ft = 92 ft

Jordan will need 92 ft of fencing.
