D and b
they are 90° angles cause you can draw your line to make a 90° angle
Step-by-step explanation:
The only face of the cube that has all the points C, F and G is the face CFGD on the right facing outwards.
Hence point D must be coplanar as it is on the same face.
1 should be b and 2 should be a
Answer:
160°
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°. The sum of angles in the given triangle is ...
x + (x +4) + 20x = 180
22x +4 = 180 . . . . . . . . . . collect terms
22x = 176 . . . . . . . . . . subtract 4
x = 8 . . . . . . . . . . . divide by 22
20x = 160 . . . . find the largest angle
The measure of the largest angle is 160°.
8.76582 × 10 to the 3rd power, that's how many hours there are in a year using scientific notation.
