In right triangle ABC, mA = 90°, cos

Mathematics
1 answer:
Debora [2.8K]2 years ago

The value of x in the triangle is 0.21

<h3>How to determine the value of x?</h3>

The given parameters are:

mA = 90°

cos(B) = 7x - 0.55

sin (C) = x + 0.71

Since the angle is a right triangle, then

C + B = 90

In a right triangle;

If C + B = 90, then

sin(C) = cos(B)

So, we have:

7x - 0.55 = x + 0.71

Evaluate the like terms

6x = 1.26

Divide both sides by 6

x = 0.21

Hence, the value of x in the triangle is 0.21

9. Look at triangle RST below.<br><br> Which side of the triangle is the longest?
Lera25 [3.4K]

Answer:

ST is longest

Step-by-step explanation:

  • <em>Theorem: </em>
  • <em>If one side of a triangle is longer than another side, then the angle opposite the longer side will be larger than the angle opposite the shorter side</em>

The values of the angles are:

  • ∠S= 50°,
  • ∠T= 60°,
  • ∠R= 180°- (50°+60°)= 180° - 110° = 70°

Since ∠R is the largest angle, the side ST is longest

Jim paddles from one shore of a lake three miles wide at 4 mph, and John paddles from the opposite shore at 5 mph. How long will
AleksandrR [38]
D= distance
t= time
s= speed

FORMULA
Distance= speed * time

STEP 1:
Find total distance
Jim's D + John's D= 3 miles

STEP 2:
Distance= (Jim's speed * time) + (John's speed * time)
D= 4t + 5t
3 miles= 9t
divide both sides by 9
3/9= t
reduce by 3
1/3 hour= t

STEP 3:
1 hour= 60 minutes
=1/3 * 60
=(60/3)
= 20 minutes

ANSWER: They will travel 20 minutes before they meet.

Hope this helps! If it does, please mark me brainliest! :)
