1 answer:

7 0

ok turn 7/5 and 3/5 into a decimal
here let me help you

3/5 = 0.6
7/5 = 1.4

1.4 / 0.6 = 2.3 repeat

then turn it back into a fraction which is 2 3/10

this is how I do it by the way.

A=63°

bekas [8.4K]

Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

A=63°
c = 7.75 inch
B = 47°

Now we know that:

$\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ$

Using the Law of Sines

$\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)$

John stands 150 meters from a water tower and sights the top at an angle of elevation of 36º. If John's eyes are 2 meters above

horsena [70]

Answer:

The height of tower $DB=111\ meters$ .

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that,

Distance between John and tower is $CE=150 \ meters$ .

Angle of elevation to the top of the tower is $\angle DEC=36$ °.

Height of John is $CB=2\ meters$ .

To Find: Height of the tower $DB$ .

So,

In triangle ΔDCE,

$Tan$ (∠ $DEC)= \frac{DC}{CE}$

$Tan (36)= \frac{DC}{150}$

$DC= tan(36)\times 150$

$DC=108.98\ meters$

Now,

To calculate the height of tower we have

$DB=DC+CB$

$DB=108.98+2$

$DB=110.98\ meters$ ≈ $111 \ meters$

Therefore,

The height of tower $DB=111\ meters$ .

Can someone help me? I'm lost.

KengaRu [80]

First step is to find R
use The equation QR =43

R=43/Q
now since we have R plug that into PR= 9x - 31

P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9

Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer

Hope this helps! xD
would not mind if you put it as the brainliest answer
