Answer:
m < D = 7.14°
Step-by-step explanation:
Use the Pythagorean theorem of a right triangle
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
Substitute in known values
[tex]7^{2}[/tex] + [tex]b^{2}[/tex] = [tex]10^{2}[/tex]
49 + [tex]b^{2}[/tex] = 100
[tex]b^{2}[/tex] = 100 - 49 = 51
b = [tex]\sqrt{51}[/tex] = 7.14
Hope this helps :)
