Help: All triangle have angles that add up to 180, for isosceles triangles 2 of the angles are the same 1 is different. You need to know at least 1 angle. A = Angle.
A times 2 - 180 = x
Two angles are the same 1 is gotten from the equation
125(greater than or equal to) 0.80b+65
X can be less than or equal to 75
Answer:
<em>the father has 8 children</em>
Step-by-step explanation:
The cake = 1 whole = 12/12 = 3/3
If the father ate 1/3 of the cake, we know that 2/3 of the cake was divided amongst his children
How many 1/12's can fit into 2/3?
- (2/3) / (1/12) --> (2/3) x (12/1) = (24/3) = 8
If 8 1/12-pieces can fit into 2/3 of a cake, <em>the father has 8 children</em>.
Answer:
30 miles
Step-by-step explanation:
Before finding the perimeter of the given right angled triangle, we need to find the length of a.
We'll be using pythagoras property to find the value of a.
According to the pythagoras property, sum of the squares of base and perpendicular is equivalent to the square of hypotenuse.
Here,
- Hypotenuse = 13 mi
- Base = 12 mi
- Perpendicular (a) = ?
→ H² = B² + P²
→ H² - B² = P²
→ (13 mi)² - (12 mi)² = a²
→ 169 mi² - 144 mi² = a²
→ 25 mi² = a²
→ √(25 mi²) = a
→ <u>5 mi = a</u>
We know that,
- Perimeter of ∆ = Sum of all sides
→ Perimeter = 13 mi + 12 mi + a
→ Perimeter = 13 mi + 12 mi + 5 mi
→ Perimeter = 30 miles
<u>Perimete</u><u>r</u><u> </u><u>of</u><u> </u><u>the </u><u>triangle</u><u> </u><u>is</u><u> </u><u>3</u><u>0</u><u> </u><u>mi</u><u>l</u><u>e</u><u>s</u><u>.</u>
The answer is C let me know if it was wrong but it should be correct :)
