Answer:

Step-by-step explanation:

since the slope is 5, 1/5x or -1/5x cannot be the slope. since the slope isn't negative it also cancels out -5x. 5x can be your only slope and that is in answer B.

In ΔBCD, the measure of ∠D=90°, the measure of ∠B=71°, and DB = 67 feet. Find the length of BC to the nearest tenth of a foot.

PSYCHO15rus [73]

Answer:

in triangle BCD

relationship between base and hypotenuse is given by cos angle

cos 71=b/h

cos71=BD/BC

cos71=67/x

x=67/cos71=205.8ft.

the length of BC to the nearest tenth of a foot is 206ft.

Thethree sides of a triangle measure 810 and 12 units is this a right angle?

Alja [10]

Answer:

The given triangle is NOT A RIGHT ANGLED TRIANGLE.

Step-by-step explanation:

Here, the three given sides of the triangle are:

8 units, 10 units and 12 units

Now, for any triangle to be a right angle:

by the PYTHAGORAS THEOREM:

$(Base)^2 + (Perpendicular)^2 = (Hypotenuse)^2$

The longest of all sides id the hypotenuse.

⇒ H = 12 units

Let us assume, B = 8 units, P = 10 units

Now, here checking the condition:

$(8)^2 + (10)^2 = 64 + 100 = 164 \neq (12)^2 = 144\\\implies (B)^2 + (P)^2 \neq (H)^2$

Hence, the given triangle is NOT A RIGHT ANGLED TRIANGLE.
