Answer:
- angle at A: 51°
- base angles: 64.5°
Step-by-step explanation:
The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.
The base angles at B and C are the complement of half this value, or ...
90° -(51°/2) = 64.5°
The angle measures in the triangle are ...
∠A = 51°
∠B = ∠C = 64.5°
Answer:
11
Step-by-step explanation:
4x - y = 13 >>>> y = 4x - 13
2x + y = 17 >>>> y = -2x + 17
so
4x - 13 = -2x + 17
4x + 2x = 17 + 13
6x = 30
x = 5
y = 4x - 13 = 4(5) - 13 = 7
then
3y - 2x = 3(7) - 2(5) = 21 - 10 = 11
Answer:
Step-by-step explanation:
Given
--- height
--- initial velocity
--- acceleration
Required
The velocity when he hit the water
The velocity is then calculated using:
This gives:
Solve for v
Answer:
5 sqrt2.
Step-by-step explanation:
5 sqrt 8 - sqrt 18 - 2 sqrt 2
= 5 sqrt(4*2) - sqrt(9*2) - 2 sqrt2
= 5 sqrt4*sqrt 2 - sqrt 9*sqrt 2 - 2 sqrt2
= 10 sqrt2 - 3 sqrt2 - 2 sqrt 2
= 5 sqrt2.
(z • 5) + 8
You can edit it in other ways like 5z + 8 if you want
