Answer:

New elevation = 122 meter below

Step-by-step explanation:

Given:

Current status = 77 meter below

Additional dive = 45 meter

Find:

New elevation

Computation:

New elevation = Current status + Additional dive

New elevation = 77 + 45

New elevation = 122 meter below

PLEASE HELP ASAP ILL GIVE BRAINLIEST!!!!!<br><br>find measure of arc MK

Gwar [14]

Answer:

Arc length MK = 15.45 units (nearest hundredth)

Arc measure = 58.24°

Step-by-step explanation:

Calculate the measure of the angle KLN (as this equals m∠KLM which is the measure of arc MK)

ΔKNL is a right triangle, so we can use the cos trig ratio to find ∠KLM:

$\sf \cos(\theta)=\dfrac{A}{H}$

where:

$\theta$ is the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

Given:

$\theta$ = ∠KLM
A = LN = 8
H = KL = 15.2

$\implies \sf \cos(KLM)=\dfrac{8}{15.2}$

$\implies \sf \angle KLM=\cos^{-1}\left(\dfrac{8}{15.2}\right)$

$\implies \sf \angle KLM=58.24313614^{\circ}$

Therefore, the measure of arc MK = 58.24° (nearest hundredth)

$\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}$

Given:

r = 15.2
∠KLM = 58.24313614°

$\implies \textsf{Arc length MK}=2 \pi (15.2)\left(\dfrac{\sf \angle KLM}{360^{\circ}}\right)$

$\implies \textsf{Arc length MK}=\sf 15.45132428\:units$

Evgesh-ka [11]

Answer:

$Bill\to 9\ years$

$H \to 16\ years$

Step-by-step explanation:

Let

$H \to Hoang$

$B \to Bill$

Currently:

$H = B + 7$

Two years ago

$H - 2 = 2 * (B -2)$

Required

H and B

We have:

$H - 2 = 2 * (B -2)$

Open bracket

$H -2 =2B - 4$

Add 2 to both sides

$H -2+2 =2B - 4+2$

$H =2B -2$

Substitute $H = B + 7$

$B + 7 =2B -2$

Collect like terms

$2B - B =7+2$

$B = 9$

Substitute $B = 9$ in $H = B + 7$

$H = B + 7$

$H = 9 + 7$

$H = 16$
