Question 37 the answer is about x=5.25 can someone explain to me how to do that problem without a calculator also question 39 there is supposed to be two answers i found .52 but the other one is x=2.26 and idk how to get that one and again no calculator

37) m∠x = 5.25

39) m∠x = 0.5236 and m∠x = 2.62

Step-by-step explanation:

37)

∵ cotx = -0.6 and 3π/2 ≤ x ≤ 2π

∴ tanx = -1/0.6

∵ ∠ x in the fourth quadrant ⇒ ∴ m∠x = 2π - α where α is an acute angle

∵ tanα = 1/0.6 ⇒ α =

∴ α = 1.03038

∴ m∠x = 2π - 1.03038 = 5.25

39)

∵ cscx = 2 and 0 ≤ x ≤ 2π

∴ sinx = 1/2 ⇒ +ve value

∴ ∠x is in the first quadrant or the second quadrant

∴ m∠x = α or m∠x = π - α

∵ sinα = 1/2 ⇒ ∴ α =

∴ α = 0.5236

∴ m∠x = 0.5236

∴ m∠x = π - 0.5236 = 2.6216 ≅ 2.62

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
