Answer:
30 degrees
Step-by-step explanation:
triangles have 180 degrees
right triangles have a right angle which is 90 degrees
180-90=90
90-60=30
The first one. The sum of all angles on a triangle is always equal to 180
1.6 is the nearest 10th because the 6 is a tenth .0. and 1.64 to the nearest hundredths would be 1.6 so the original number is 1.6<span />
