Please help me I really need it
Art [367]

Answer:

Angle C

Step-by-step explanation:

By applying sine rule in the given triangle,

\frac{\text{sinB}}{CD}=\frac{\text{sinC}}{BD}=\frac{\text{sinD}}{BC}

\frac{\text{sinB}}{\text{sinC}}=\frac{\text{CD}}{\text{BD}}

Therefore, sides of the given triangle will be in the same ratio as the sine of the angles.

Since, BD > BC > CD

Therefore, Opposite angles of these sides will be in the same ratio.

∠C > ∠D > ∠B

Largest angle of the triangle is angle C.

This is a picture of a small sumu
Deffense [45]

Answer:

C

Step-by-step explanation:

The rubber exercise ball is a sphere

the volume of a sphere= 4/3*pi*r3

where r = the radius of the sphere.

from the diagram, the radius = 4.5inches

Therefore, volume of the rubber ball = 4/3*pi*4.5^3 = 381.51 cubic inches

Evaluate the dot product a⃗ ⋅b⃗ of a⃗ =3i^−8j^ and b⃗ =−2i^−6j^.
Mkey [24]
The "dot product" of two vectors has several different formulas.

Since you are given the x- and y-coordinates of both vectors a and b, we can apply the formula

a dot b  = ax*bx + ay*by, where ax=x-component of vector a, by=y comp of vector b, and so on.  

So, for the problem at hand, ax * bx + ay * by becomes

3(-2) + (-8)(-6) = -6 + 48 = 42 (answer).  Note that the dot product (or "scalar product" is itself a scalar.

The measure of angle x is 25 more than 4 times the measure of its complement. Find the measure of x.
topjm [15]
- Two angles that are complements of each other add to equal 90 degrees (they are complementary angles). 
- One angle measures x degrees.
- The other angle measures 25 more than 4 times the angle that measures x degrees; it measures 4x + 25 degrees.

To find x, set the sum of these expressions (x and 4x + 25) equal to 90 and solve algebraically for x.

90 = x + (4x + 25)
90 = x + 4x + 25
90 = 5x + 25
65 = 5x
13 = x

If you wanted to find the measure of angle x, you'd substitute 13 for x in its expression, 4x + 25.

4x + 25
4(13) + 25
52 + 25
77

Answer:
x = 13
m∠x = 77°
