The required value of the acute angle x in a  right angle triangle is 20. Option A is correct.

Given that
In a right triangle, the acute angles have a relationship,

sin (2x+4) = cos(46)

To determine the value of x

<h3>What are trigonometric equations?</h3>

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.

sin (2x+4) = cos(46)  - - - - - -(1)

Since,
cos(46) = cos (90 - 44)
cos(46) = sin (44)

put it in equation 1

sin (2x+4) = sin (44)
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 20

Thus, the required value of the acute angle x in a  right angle triangle is 20. Option A is correct.

One number is 5 more than another number. their sum is −15 . what are the numbers?
Aliun [14]
X=5+y
x+y=-15

subsitute 5+y for x

5+y+y=-15
5+2y=-15
minus 5 from both sides
2y=-20
divide both sides by 2
y=-10

sub back
x=5+y
x=5-10
x=-5

the numbers are -10 and -5

A right triangle has one angle that measure 23o. The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm.
MrMuchimi

Answer:

161.8cm²

Step-by-step explanation:

solve for height which is the opposite

opp=x

sin(theata)= opp./hyp.

sin23=x/30

x=30×sin23

x=11.72cm

height=opposite

height=11.72cm

base=adjacent

base=27.6cm

½of 27.6cm=13.8

13.8cm×11.72cm=161.74 (2d.p)

161.74 rounded to the nearest tenths= 161.7

I'm not sure if it's the answer but it's the closest thing to the options
