Answer:
p = -4
Step-by-step explanation:
-3( 2+4p) + 7 = 49
Subtract 7 from each side
-3( 2+4p) + 7 -7= 49-7
-3( 2+4p) = 42
Divide by -3
-3( 2+4p) /-3 = 42/-3
( 2+4p) = -14
Subtract 2 from each side
2+4p-2 = -14-2
4p = -16
Divide by 4
4p/4 = -16/4
p = -4
The value of x in the diagram is 6.1 cm.
<h3>What is right-angle triangle?</h3>
A right-angle triangle is a triangle that has 90° as one of the angles in the triangle.
To calculate the value of x in the right-angled triangle above, we use the formula below
Formula:
- tanθ = y/x............ Equation 1
Make x the subject of equation 2
- x = y/tanθ............. Equation 2
From the question,
Given:
Substitute these values into equation 2
- x = 7/tan49°
- x = 7/1.15
- x = 6.1 cm
Hence, the value of x in the diagram is 6.1 cm.
