So to find the unknown angle, you would basically take your known variables and use this formula SohCahToa.
That formula is the primary trigonometric formula for right angled triangles.
#1. Verify first that it is a right angled triangle before you use the formula, and it is because there is the right angled sign!
#2. Choose the appropriate formula. (I choose Toa because we are given the adjacent and the hypotenuse).
#3. Plug in the known variables, then take the opposite inverse.
Tanx=1.9/3.2
Tanx=0.59
X=Tan Inverse
X=30.6
You said round to one place so that's it, unless you want to say x is 31 degrees.

Answer:

Q1) x = 17.3

y = 8.7

Q2) d = 19

Step-by-step explanation:

Question 1

Angle = 60°

Hypotenuse = x

Adjacent = y

Opposite = 15

Step 1: Find x

Sin (angle) = opposite/hypotenuse

Sin (60°) = 15/x

x = 10√3 = 17.3

Step 2: Find y

Tan (angle) = opposite/adjacent

Tan (60°) = 15/y

y = 5√3 = 8.7

Question 2

Step 1: Find the diagonal of the base

c² = a²+b²

c² = 6² + 10²

c = 2√34 = 11.7

Step 2: Find diagonal d

c² = a² + b²

d² = 11.7² + 15²

d = 19

geniusboy [140]

Answer:

V = 26d^2 + 624d

Step-by-step explanation:

Volume = Width x Depth x Height

V = 26 (d) (d+24)

Now distribute 26

V = 26d(d+24)

Then distribute 26d

V = 26d^2 + 624d

In ∆PQR, ∠P = 90degrees , PQ= 12 cm, PR=16cm. Find ∠Q

siniylev [52]

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
