Answer:

Option (a) and (d) are correct.

Step-by-step explanation:

Given : A line segment AC with B a point on it and DB making an another line segment.

We have to name the type of angle shown.

Straight angle : is an angle made by a straight line. Measure of straight angle is 180°

Right angle: is the angle whose measure is 90°

Complementary angles: are two angles whose sum is 90°

Supplementary angles: are two angles whose sum is 180°

Here, ABC forms a straight angle.

and ∠ABD + ∠DBC = 180°

Thus, ∠ABD and ∠DBC forms a pair of supplementary angles.

Option (a) and (d) are correct.

For the equation 2x - y = 1, if x = 0, then y = ?

Lostsunrise [7]

Answer:

y= -1

Step-by-step explanation:

(2) (0) − y = 1

0 + − y = 1

(−y) + (0) = 1

−y = 1

Step 2: Divide both sides by -1

Y = −1

Triangles Unit Test part 1 A length of rope is stretched between the top edge of a building and a stake in the ground. The head

musickatia [10]

Answer:

The building is 32 feet tall.

Step-by-step explanation:

Consider the figure drawn below representing the given scenario.

AB represents the height of building, BC is the distance between the stake and building, C represents the stake at ground level, and DE represents the height of the tree growing halfway between building and stake.

Since the tree is growing halfway between B and C, therefore, the point E divides the line segment BC into 2 equal parts.

Therefore, $BE = EC$ or E is the midpoint of BC.

Also, from the figure, it is clear that both tree and building are vertical to the ground. So, DE || AB.

Now, from converse of mid-segment theorem, if a line passes through the midpoint of one side of a triangle and also parallel to the third side, then the line also passes through the midpoint of the second side and half the length of the third side (parallel side)

So,

$DE=\frac{1}{2}\times AB\\\\16=\frac{AB}{2}\\\\AB=16\times 2=32\ ft$
