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°.
2.2=4
2.7=14
5-4+14-5=1+14-5=15-5=10
Good Luck!
X= is the number looked for.
56% of x=14
We suggest this equation:
(56/100)x=14
x=(14*100)/56=25
Solution: 25
Answer:
540°
Step-by-step explanation:
If a triangle (3 sides) has 180 degrees then we can figure out the degrees in a pentagon.
180° + 360° = 540°
How? The "top" part could be seen as a triangle (180 degrees), and we know that a quadrilateral's angles add up to 360 degrees, so when we add them together we get out answer!
