Answer: 60°
Step-by-step explanation: this is because angles 1 and 3 are the same, so if line y is moved 5 degrees to the right (clockwise), then it expands angles 1 and 3, so you add 5° to the already known 55°. Hope I helped!
Answer:
5) 9
6) 11 2/3
Step-by-step explanation:
Use the Pythagorean Theorem.
5) a²+5.6²=10.6²
a²+31.36=112.36
a²=81
a=√81
a=9
6) a²+4²=12.3333²
a²+16=152.11111
a²=152.11111-16
a²=136.1111
a=√136.1111=11.6666
