Question

Use the figure for #10-13. m/ABD = 127⁰

10. Find m/ABC =
A
II. Find m ZACB =
12. Find m/ ACD =
13. Find m/ CAB
B
D

Answer 1

ABC =146.5

ACB=67

ACD=127

CAB=146.5

Explanation:

ABD=127

ACD=127

BCD=60 ( Being equilateral triangle)

60+x=127

x=67

ACB=67

CAB=CBA=y (let)

y+y+ACB = 360 ( Sum of int angles of triangle)

2y+67=360

2y=293

y=146.5

CAB=146.5

ABC=146.5
