Answer:
In ΔIJK, the measure of ∠K=90°, JK = 90 feet, and KI = 54 feet. Find the measure of ∠I to the nearest tenth of a degree.
Step-by-step explanation:
The other angle will be 45 degrees ( 180-90-45=45 angle sum of triangle)
Thus this is an isoceles triangle—> x = y
Using Pythagoras’s theorem, 2x^2 = 7^2= 49
Thus x = 7/rt(2) or -7/rt(2) , then reject negative values and rationalise to get 7rt(2)/2 for x, thus x = y = 7rt(2)/2
