Answer:
4°
Step-by-step explanation:
Since it is said that the angles are corresponding angles so we know that corresponding angles are equal then, 
<1 = <2
3x - 7 ° = x - 1°
3x - x = 7° - 1°
2x = 8°
x = 8° / 2
Therefore x = 4°
Hope it will help you :)
 
        
             
        
        
        
Answer:
x ≈ 2879.4 m
Step-by-step explanation:
Measure of ∠DAC = 10°
Measure of ∠DAB = 90°
Measure of ∠BAC = 90° - 10° = 80°
By applying cosine rule in ΔABC,
cos(80°) = 
               = 
0.17365 = 
x = 
x = 2879.36
x ≈ 2879.4 m
