Answer:
7 sqrt(2)= BC
7 sqrt(2)= AB
Step-by-step explanation:
sin 45 = opp / hyp
sin 45 = BC / 14
Multiply each side by 14
14 sin 45 = BC
Sin 45 = sqrt(2)/2
14 sqrt(2)/ 2 = BC
7 sqrt(2)= BC
cos 45 = adj / hyp
cos 45 = AB / 14
Multiply each side by 14
14 cos 45 = AB
cos 45 = sqrt(2)/2
14 sqrt(2)/ 2 = AB
7 sqrt(2)= AB
Answer:
Step-by-step explanation:
3a3 (-3a2 + 5a - 5)
Product: -9a5 + 15a4 - 15a3
3a3 (-3a2 + 5a - 5)
Answer:
Yes
(-4,-2) is a solution of a given system of equation
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the equation
y = 2 x + 6 ..(i)
Given point (-4,-2)
substitute x =-4 and y = -2 in equation (i)
-2 =2(-4) +6
-2 = -8+6
-2 =-2
∴ The point satisfies the given equation
If the angles of the triangle are 50, 90, 40 degrees, then only 1 triangle can be made. Because if you change the sides, the angles would change
