Question

Slove These Please And Explain Too​

Answer 1

Answer:

6)SSA is not a criteria for congruence of triangle

5)5x+3x+7x=180(angle sum property of triangle)

15x=180

x=12

5(12)=60

3(12)=36

7(12)=84

Hence all angles are less than 90 so it is acute angled triangle

Hope this helps

Answer 2

Answer:

PLEASE MARK ME AS BRAINLIEST

Step-by-step explanation:

5b)obtuse angled triangle

Because 3^2 +5^2 = 9+25=34

Hence they form obtuse angle

6c)SSA

Because all others are criterion but this is not, you can check your book
