Answer:
The larger angle is 70°
And The smaller angle is 20° .
Step-by-step explanation:
Given as :
The ratio of two complementary angles = 7 : 2
Let The larger angle = 7 x
And The smaller angle = 2 x
Now, According to question
<u>Complementary angle is define as when two angles were added to make right angle i.e 90° are complementary to each other .</u>
So, here
7 x + 2 x = 90°
Or, 9 x = 90°
∴ x = 
i.e x = 10°
Now, putting the value of x
So, The larger angle = 7 × 10° = 70°
And The smaller angle = 2 × 10° = 20°
Hence, The larger angle is 70°
And The smaller angle is 20° . Answer
The answer is boxed in. follow the arrows.
Let
P(h)= probability of selecting heart = 13/52= 1/4
similarly
P(s)= probability of selecting spade =1/4
P(c)= probability of selecting club =1/4
P(d)= probability of selecting diamond =1/4
a)
P(h or s)= P(h)+P(s)= 1/4+1/4=2/4=1/2=0.5
b)
P(h or s or c)=P(h)+P(s)+P(c)=1/4+1/4+1/4=3/4=0.75
c)
P(2 or a diamond)=n(2heart, 2spade,2club,13 diamonds)/total number of cards
=(1+1+1+13)/52=16/52=4/13=0.3
or we could solve it as follows:
P(2 or a diamond)=P(2)+P(diamond)-P(2diamond)=4/52 + 13/52 + 1/52 = (4+13-1)/52=16/52=0.3
