Answer:

∠Q  = 53.13 degrees

Step-by-step explanation:

Given that ∆PQR, ∠P = 90degrees , this means that the triangle is a right angled triangle

Hence using the notation

SOH CAH TOA

where S is sine, C is cosine, T is tangent and O, A and H represents the size of the opposite, adjacent and hypotenuse sides

Considering  ∠Q and the given sides

PR=16cm is the opposite side,

PQ= 12 cm is the adjacent side hence we use TOA

Tan Q = 16/12 =

Q = Arc tan 16/12

= 53.13 degrees

mars1129 [50]

Answer:

2,125m

Step-by-step explanation:

85% = 85/100

85/100 = x/2500m

Solve by cross multiplying

85(2500) = 100(x)

212,500 = 100x

Divide by 100 on both sides

x = 2,125m

Hope this helps :)

Y’all I need help with this
topjm [15]

Answer:

k = 5

Step-by-step explanation:

Since the quantities are in direct proportion then the equation relating them is

y = kx ← k is the constant of proportion

The y- axis is number of cups and x- axis is pounds of sugar

To find k use any of the 5 points highlighted on the graph

Using (8, 40 ), then

40 = 8k ( divide both sides by 8 )

5 = k
