False because the interior angles of any triangle needs to add up to 180°. In an isoceles triangle, the base angles of the triangle are equal so 43° + 43° = 86°. If the vertex angle is 80° then the total is 166°. This doesn't meet 180°, so the vertex angle must be 94° if the base angles are 43°. If the vertex angle must be 80°, then the base angles have to be 50°.
Answer:
7000
Step-by-step explanation:
Answer:
a) 10.95
b) 76.65
Step-by-step explanation:
To find the unit price of Ben's video games, divide 43.80 by 4, which is equal to 10.95. So, the unit price is 10.95 at Ben's Game World.
Then, using the unit price we found earlier, multiply 10.95 by 7, which will gives us the cost of 7 games at Roberto's Electronics. You'll get 76.65. So, the cost of 7 games at Roberto's Electronics, using the same unit price at Ben's Game World, would be 76.65.
Hope this helps :)
Okay so first you have to factor out anything they have in common and you can take out a x and 4
so then it turns into 4x(x-5)
