Answer:
b
Step-by-step explanation:
More than one triangle can be formed by three angles measuring 75°, 45° and 60°. Solution : We know that, The sum of the measures of all angles of a triangle should be equal to 180°. Hence, the angles 40° , 50° and 60° cannot form a triangle as their sum is 150°.
Answer:
125
Step-by-step explanation:
50 x 150% = 75
75 + 50 = 125
Answer:
Option E
Step-by-step explanation:
We know that
√25 = 5
√36 = 5
√30 lies between √25 and √36.(5 and 6l
Hence, Option E is correct
Answer:
x = 42 - 4
x = 38
Step-by-step explanation:
Given that :
Initial number of plane models = x
Number of additional models built = 4
Total number of planes = 42
Total = initial amount + additional amount
42 = x + 4
Make x the subject
42 - 4 = x + 4 - 4
x = 42 - 4
X + 4 = 42
X = 42 - 4
X = 38
