Answer: (5,2)
Step-by-step explanation:
Given equations:
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get
Adding equation (3) and (4), we get
Substitute x=5 in equation (4), we get
Hence, the solution of the both equations is (5,2).
First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.
