Answer:
B
Step-by-step explanation:
Answer:
Just count the number of zeros:
Step-by-step explanation:
There are 4 zeros, so the answer is 5 x 10^4.
Answer:
36°
Step-by-step explanation:
Like your other question, the angles of the triangle must add up to 180. The tangent line is perpendicular to the center, so the angle must be 90°.
90° + 54° + 36° = 180°
Answer:
Angle CDE equals 155 degrees :D
Step-by-step explanation:
parallel lines
since the left angle is 57, angle BAE is also 57
180-57=123
right angle=90
115+90+123+57=385
540-385=155
thus, angle CDE equals 155 degrees
EF=9 cm. Both triangles are the same.
