6(2(5)-4)= 6(10-4)= 6(6)=36 so your answer is 36
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.
