Answer:
65.46 units
Step-by-step explanation:
Given the information:
- The vertex angle of an isosceles triangle measures 26°
=> the leg angle is:
= (180° - 26° )/2
= 77°
Let x is the length of the leg side (x>0)
We use cosine law to find x, we have:
=
Because the isosceles has two equal leg sides
<=>
= 2
- 1.79
<=> 0.21
=
<=> 
<=> x = 65.46 units
Hope it will find you well.
Answer:
7 - 2.25
= 7 - 2
= 5 - 0.25
= 4.75
9 - 1.9
= 9 - 1
= 8 - 0.9
= 7.1
I hope this helps and that you have a great day!

Answer:
7. 2355 m
8. 1570 km
9. 157 cm
10. 40.82 m
Step-by-step explanation:
The circumference of a circle is pi * diameter or 2 * pi * radius.
If you are given the diameter, just multiply it by pi, 3.14.
If you are given the radius, then multiply the radius by 2 and then by pi, 3.14.
7. d = 750 m
circumference = pi * d = 3.14 * 750 m = 2355 m
8. d = 500 km
circumference = pi * d = 3.14 * 500 km = 1570 km
9. r = 25 cm
circumference = 2(pi)r = 2 * 3.14 * 25 cm = 157 cm
10. r = 6.5 m
circumference = 2(pi)r = 2 * 3.14 * 6.5 m = 40.82 m
