so,
angle DAB = 25° + 35°
= 60°
now,
angle DAB + angle ADC. = 180°
or, 60° + ADC = 180°
or, ADC = 180° - 60°
Therefore, ADC = 120°
therefore, the angles of the PARALLELOGRAM are 60° and 120°.
If you want to know how fast the professional runner is going, you need to multiply 3 1/3 by 1 1/4 since the professional is 1 1/4 times faster. So, your answer is 4 1/6.
Step-by-step explanation:
a) sample space = 10
I.e the total number of possible outcomes
b) A = {7,8,9,10 }
B = {4,9
c) A U B = {4,7,8,9,10}
d) pr (A) = no of events in A÷ total sample space
pr (A) = 4/10
=2/10
e) pr( A U B) = 5/ 10
= ½
Answer:66.4
