Answer:

steps below

Step-by-step explanation:

∠1 = 48

∠2 = 180 - ∠1 = 132 (adjacent angle, supplementary)

∠3 = ∠1 = 48 (vertical angle)

∠4 = ∠2 = 132

In each problem, angle C is a right angle. Solve each triangle rounding answers to the nearest

ryzh [129]

Answer:

B = 61°

A = 29°

a = 10

Step-by-step explanation:

We are given;

c = 16, b = 14

Since we are told that C is a right angle, it means that C = 90°

Thus using sine rule, we have;

c/sin C = b/sin B

16/sin 90 = 14/sin B

16/1 = 14/sin B

sin B = 14/16

sin B = 0.875

B = sin^(-1) 0.875

B ≈ 61°

Now, since C is a right angle, it means that c will be the hypotenuse of the triangle.

Thus, from pythagoras theorem, If the other side of the triangle is a, then;

a² + b² = c²

a² + 14² = 16²

a² = 16² - 14²

a² = 256 - 156

a² = 100

a = √100

a = 10

Since we know B and C, we can find A because sum of angles in a triangle is 180°.

Thus;

A = 180 - (B + C)

A = 180 - (61 + 90)

A = 29°

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 8

julsineya [31]

Good afternoon,

First side= 8cm
Third side= x
Second side= 2x-4

We know that the sume of the lenghts of any two sides must be greater than the third side, so:

$Second \,\,\,\,side+Third\,\,\,\,side>First\,\,\,\,side \\ 2x-4 + x >8 \\ 3x>12 \\ x>4
$

Answer: Third side= x ; where: x>4 or (4,+infinity)
Second side= 2x-4 ; where: x>4 or (4,+infinity)

In a recent u.s.census, the population of Illinois was 12,419,293. What is this population after

ExtremeBDS [4]

12,419,293

an increase of 100,000 = 12,519,293
an increase of 1,000,000 = 13,419,293
a decrease of 10,000 = 12,409,293

Parallel, intersecting or skew?

const2013 [10]

Two lines are:

Parallel if they don't intersect and lie on the same plane
Intersecting if...well, they intersect at one point
Skew if they don't intersect and they lie on two different planes

So, we have:

AB and BC intersect at point B
AE and BF don't intersect, but both lie on the plane AEFB
EF and AD don't intersect and don't lie on a common plane
ABC and ABF intersect on segment AB
AED and BFC are parallel (they're both perpendicular to plane ABC)
