Given: ∆PQR, m∠R = 90° m∠PQR = 75° M ∈ PR , MP = 18 m∠MQR = 60° Find: RQ

tensa zangetsu [6.8K]

Answer: RQ= 8.99 ( approx)

Step-by-step explanation:

Let MR= x

Since, In triangle, PRQ, tan 75°= $\frac{18+x}{RQ}$

⇒ RQ= $\frac{18+x}{tan 75^{\circ}}$

Now, In triangle MRQ,

tan 60°= $\frac{18+x}{RQ}$

⇒ RQ= $\frac{x}{tan 60^{\circ}}$

On equating both values of RQ,

$\frac{18+x}{tan 75^{\circ}}=\frac{x}{tan 60^{\circ}}$

⇒ $\frac{18+x}{x}=\frac{tan 75^{\circ}}{tan 60^{\circ}}$

⇒ $\frac{18+x}{x}=2.15470053838$

⇒ $18=2.15470053838x-x$

⇒ $x=15.5884572681$ ≈15.60

Thus RQ=8.99999999999≈8.99

The sum of two integers is 74. The larger is 26 more than twice the smaller. Find the two integers.

hodyreva [135]

To find the answer,we can set up two equations:

Let the integer be x and y seperately,and x be the larger number:

x+y=74
y=74-x....(1)

x-2y=26...(2)

Put (1) into (2):

x-2(74-x)=26
x-148+2x=26
3x=26+148
x=174/3
x=58

Put the above answer into (1):

y=74-58
y=16

Therefore,the answer is x=58, y=16.

Hope it helps!

Fencing costs $10 per foot. Frances had a rectangular garden that is 4 feet wide and 5 feet long. How much money will Frances ne

kicyunya [14]

Answer:

$180

Step-by-step explanation:

1. Find the perimeter: 2w + 2L

2(4) = 8 + 2(5) = 10

8 + 10 = 18 feet of fencing

2. multiply the cost per foot (10) by the number of feet (18)

10*18 = 180
