Answer:

A = 50°

Step-by-step explanation:

(2x - 10) + (x + 30) + 70 = 180 \\ 2x + x = 180 + 10 - 30 - 70 \\ 3x = 90 \\ x =  \frac{90}{3}  \\ x = 30

Then

a = 2x - 10 \\ a = 2(30) - 10 \\ a = 60 - 10 \\ a = 50

Actually Welcome to the Concept of the Triangles.

Since we know that, the Angle sum property of a triangle is equal to 180°.

means that, <A + <B + <C = 180°

so we can write as,

==> 2x-10 + x + 30 +70 = 180°

===>3x +90 = 180

==> 3x = 90

hence, x = 30°

so now, substitute angle x,

So angle A is => 2(30)-10 => 60-10 = 50°

hence Angle A = 50°.

Answer:

x=85^{\circ}

Step-by-step explanation:

The sum of the interior angles of any polygon with five sides is equal to (5-2)\cdot 180=3\cdot 180=540^{\circ}. Therefore, we can set up the following equation and solve for x:

115+95+115+130+x=540,\\455+x=540,\\x=\boxed{85^{\circ}}

In order to figure out who will go first in a game, your friend asks you to pick a number between 1 and 25. What are the possibl
siniylev [52]

Answer:

Step-by-step explanation:

The possible outcomes include 1, 2, 3, etc., up through 25.  This in itself is insufficient to specify who will go first.  There must be some further criteria.

Suppose each player chooses and announces a number from this set by writing it down on a scrap of paper which is placed face-down on the table.  The person who chooses the smaller number goes first.  Or, the person who chooses the larger number goes first.

A one-celled organism measures 32 mm in length in a photograph. If the photo has been enlarged by a factor of 100, what is the a
larisa86 [58]

32 mm = length × 100

(32 mm)/100 = length . . . . . divide both sides by 100

0.32 mm = length

The actual length of the organism is 0.32 mm.
