60-12= 48
48/8= 6
Step-by-step explanation:
If Q is the midpoint of PR
Then PQ + QR = PR
(6x + 25) + (16 - 3x)
group the same terms and add them
(6x - 3x) + (25 + 16)
Hence PR = (3x + 41)
But to find the value of PR....If Q is the midpoint....then PQ = QR...since they are both half lengths of PR;
; 6x + 25 = 16 - 3x
; 6x + 3x = 16 - 25...;9x = -9
Hence the value of...x = -1
Then substitute the value of x into the equation of PR....3x + 41
;3(-1) + 41
;-3 + 41
Hence PR = 38
Answer:
x = 58°
Step-by-step explanation:
Fact 1) Recall the fact that angles in a triangle add to 180°
Fact 2) Recall the fact that angles on a straight line add to 180°
The first angle we can work out is BAC using fact 2
114 + ? = 180
? = ( 180 - 114 )
? = 66
∠ BAC = 66
Now that we have angle BAC we can utilise the fact angles in a triangle add to 180°, so we can set this equation up
x + 66° + 56° = 180°
x + 122° = 180°
x = ( 180 - 122 )
x = 58°
