Find the value of x and m∠HKL.

frosja888 [35]

Answer:

x = 25 degrees ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25

Find the area of a triangle formed by placing the vectors [3, 6] and [7, 1] tail-to-tail.

Usimov [2.4K]

Answer:

a. $A=10u^{2}$

b. View graph

c. 6.40u

Step-by-step explanation:

knowing that the triangle area is equal to base by heigh between two, then:

$A=\frac{bh}{2}=\frac{5*4}{2}=10u^{2}$

The length of the longest altitude of your triangle is:

$c^{2}=a^{2}+b^{2}=5^{2}+4^{2}=25+16=41\\ c=\sqrt{41}=6.40u$

finally it can be seen that the position of the triangle does not matter, as long as the base and heigh are maintained, the area of the triangle will be the same

Find the volume of a cone with a diameter of 7 inches and a height that is 4 times the radius. Use 3.14 for pi, and round your a

Tatiana [17]

Answer:

179.50 $in^{3}$

Step-by-step explanation:

The equation for volume of a cone is:

$V=\pi *r^{2} *\frac{h}{3}$

The radius is half of the diameter so r= 3.5 in

The height is 4 times the radius so h=14

$V=3.14*3.5^{2} * \frac{14}{3}$

V= 179.50 $in^{3}$
