Answer:
Step-by-step explanation:
Everything is right except the second one. It is acute as all the angles are under 90 degrees.
A^2 + b^2 = c^2 a=4 b= 6
4^2 + 6^2 =52
square root that:
c=2 square root 13 exactly or 7.2 approximately <span />
2x^2 = 2
so x needs to equal 1 since 2*1 = 2
4x+6=3x+10 so x=4, to find the measure of KJL, plug in x into the equation 4x+6. angle KJL=22°
