in angle HIJ the measure of angle J is equal to 90° HI is equal to 88 ft,and IJ=62ft . find the measure of angle I to the earest tenths of a degree

Respuesta :

Answer: [tex]45.21^{\circ }[/tex]

Step-by-step explanation:

Given

[tex]\angle J=90^{\circ }[/tex]

HI=88 ft

IJ=62 ft

From the figure, we can write

[tex]\cos I=\frac{IJ}{HI}=\frac{62}{88}=\frac{31}{44}\\I=\cos^{-1} (\frac{31}{44})=45.207^{\circ }\approx 45.21^{\circ }[/tex]
