Answer:
117
Step-by-step explanation:
Sum of all the angles of a triangle is 180
Let the third angle be 'x'
41 + 22 + x = 180
63 + x = 180
x = 180 - 63
x = 117
Yes, set up your proportion: x/21 = 10/14
Cross multiply 14x = 210
Divide both sides by 14 and x= 15 cm
Yes because it is a linear equation
Answer:
and 
Step-by-step explanation:
(a)
Expressing as a fraction
( divide numerator/ denominator by 2 )
= ← in simplest form
(b)
Expressing as a fraction
( divide numerator/ denominator by 10 )
= ← in simplest form
Since one watermelon seed is 0.4 long, you can multiply 0.4 by 112
0.4 x 112 = 44.8
So it will be 44.8 long
