Answer:

a = 35°

b = 55°

c = 110°

Step-by-step explanation:

a = 35

(Vertically opposite angles)

b = 180 - 90 - 35

b = 55

(Total angle in a triangle is 180)

c = 180 - 70

c = 110

(Supplementary angles)

Answer:

a = 35°, b = 55°, and c = 110°

Step-by-step explanation:

Notice that angle a is a vertical angle with the angle marked 35 degrees. Vertical angles are those that are formed at the intersection of two lines. By definition, they are equivalent, so a = 35 degrees.

Angles a and b are part of a 90 degree, right triangle. Since all the angles of a triangle add up to 180, we can write: a + b + 90 = 180. Substitute 35 for a and solve for b:

35 + b + 90 = 180

b + 125 = 180

b = 55 degrees

Notice that angle c is on the same line as the angle marked 70 degrees. This means that these two angles are supplementary; in other words, they add up to 180. So: c + 70 = 180. Then, c = 110.

Thus, a = 35°, b = 55°, and c = 110°.

Determine if the following lengths could represent a triangle. If they can, determine if the triangle, is acute, obtuse, or righ
stiks02 [169]

9514 1404 393

Answer:

  A. no

  B. no

  C. obtuse

Step-by-step explanation:

For side lengths to form a triangle, the sum of the shorter two must exceed the longest.

A. 5 + 8 = 13 . . . . a line segment, not a triangle

B. 7 + 12 < 26 . . . . no closure, not a triangle

C. 11 + 15 > 20 . . . . a triangle. A picture shows it to be obtuse

  You can also compare 11² +15² vs 20² ⇒ 346 vs 400. The long side is too long for a right triangle, so the triangle must be obtuse. (The Pythagorean theorem tells you a right triangle with those legs would have a long side of √346 = 18.6.)

Can someone solve this Im to lazy !
Sladkaya [172]
Not impressed that you consider yourself "too lazy" to at least get started on the solution of this problem.  Why not "give it the old college try?"

Start by  choosing letters to represent the unit cost of each popcorn and drink:
p:  popcorn, d:  drink.

Then 2p + 3d = $22.25 and 12p+4d=$39.00
Note that the unit of measurement of all 6 terms here is " $ ".

Solve this system of linear equations simultaneously:

2p + 3d = $22.25
12p+4d=$39.00

In your shoes I would mult. the first equation by -6 and then combine the result with the second equation.  p will temporarily disappear, and you'll be left with an equation in d only, enabling you to find the unit cost of a drink.

Come on.  Show your stuff.  You'll need to respond through Comments.
