Answer:

17.97=x

Step-by-step explanation:

tan theta = opposite side/ adjacent side

tan 38 = x /23

Multiply each side by 23

23 * tan 38 = x/23 * 23

23 tan 38 = x

17.96956941 =x

To the nearest hundredth

17.97 =x

Help me please AS soon as possible please just this one question

Answer:

The largest side of given triangle is: AB

Step-by-step explanation:

In order to find the largest side, we have to find all the triangles first.

The two angles at point A will sum up to 180° as the angles on the straight line are supplementary.

So,

136 + Angle\ A = 180\\Angle\ A = 180-136 = 44

∠A = 44°

∠C = 71°

The sum of interior angles of a triangle is 180°

Using this:

∠A+∠B+∠C = 180°

44°+∠B+71° = 180°

∠B+115° = 180°

∠B = 180°-115°

∠B = 65°

In a triangle, the side opposite to the largest angle is the largest. In the given triangle, ∠C is the largest so the side AB which is opposite to ∠C is the largest.

Hence,

The largest side of given triangle is: AB

Can any help me please
PSYCHO15rus [73]
A = 8i + 6j
b = 4i + 5j

ab = (8i + 6j)(4i + 5j)
ab = 8i(4i + 5j) + 6j(4i + 5j)
ab = 8i(4i) + 8i(5j) + 6j(4i) + 6j(5j)
ab = 32i² + 40ij + 24ij + 30j²
ab = 32i² + 64ij + 30j²
ab = <32, 30>

The answer is D.
