a=9units

Answer:

solution given:

c=40° exterior corresponding angle

In right angled triangle

<c°+B°+90°=180° [Sum of interior angle of a triangle is 180°

B°=180°-40°-90°=50°

Relationship between base and hypotenuse is given by cos angle

Cos c°=base/hypotenuse

Cos40°=a/12

a=Cos40°×12=9.19or 9 units

1/5+1/7+3/21 the answer is

inessss [21]

Answer:

Step-by-step explanation:

We need to get all the fractions with a common denominator before we can solve the problem.

The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.

1/7 = 3/21

Add

$\frac{3}{21} + \frac{3}{21} =\frac{6}{21}$

6/21 = 30/105

1/5 = 21/105

$\frac{30}{105} + \frac{21}{105} = \frac{51}{105}$

Simplify

$\frac{51}{105} / \frac{3}{3} =\frac{17}{35}$

<h3>ANSWER: 17/35</h3>

I'm always happy to help :)
