Answer:

Option (2)

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(42°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(42°) = $\frac{6}{\text{Width}}$

Width = $\frac{6}{\text{tan}(42)}$

Width = 6.67

Therefore, width of the given triangle is 6.67 units.

Option (2) is the correct option.

Whats the distance between points p1=(-3,5) P2=(4,2)

leva [86]

Step-by-step explanation:

First, find the vector.

= (4,2) - (-3,5)

= (4-(-3),2-5)

= (7,-3)

And then, find the distance.

= √(7² + (-3)²)

= √(49 + 9)

= √58 ✓

Need more points ??? solve this .....only first part for 50 points .....and follow me also!

leonid [27]

Answer:

see below

Step-by-step explanation:

= √(3 + 4i)

= 2 + i

ii.

= √(-8 + 6i)

= √2(-4 + 3i)

iii.

= √(-40 - 42i)

= √-2(20 + 21i)

iv.

= √i

= $\sqrt{\frac{2 + 3i}{5 - 4i} } +\sqrt{\frac{2-3i}{5+4i} }$

= $\sqrt{\frac{-2+23i}{41} } +\sqrt{\frac{2-3i}{46} }$

at a local pizza parlor, the large pies have a diameter of 16 inches. each large pie can be cut into either 8 slices or 12 slice

mezya [45]

You can calculate the area of the whole pizza according to the formula: S=1/2*π*r². And the area of 8 piece is 1/8S while the area of 12 piece is 1/12S. The answer should be 1/8S-1/12S=4/3π.
