Answer:

  • \bf x=7^o

Step-by-step explanation:

When two parallel lines are crossed by a transversal, co-interior angles They are called co-interior angles.  The sum of the two angles on the same side of the transversal is always 180°.

\bf 120^o+7x+11=180^o

\bf 7x+120+11=180

\bf 7x+131-131=180-131

\bf 7x=49

\bf \cfrac{7x}{7}=\cfrac{49}{7}

\bf x=7^o

Answer:

x = 7

Step-by-step explanation:

corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line

one is an obtuse and one is an acute angle in which sum up to 180°

(120°) + (7x + 11) = 180°

120° + 7x + 11 = 180°

131° + 7x = 180°

131° - 131° + 7x = 180° - 131°

7x = 49°

7x/7 = 49°/7

x = 7°

plug x in to check:

7(7) + 11 = 49 + 11 = 60

7 worms, 3 beetles, 2 lizards
<span>I found this by first doing the calculations for the number of legs (26). First, I added the legs for the 3 beetles together to get 18 legs. Then I added the legs for 2 lizards (8) to the beetles’ legs to get 26 legs in total.To find the number of heads I added the number of lizard heads (2) and beetles heads (3) to get five heads. Then I added the 7 worm’s heads to the lizard and beetles heads to get 12 heads in total.</span>

Firlakuza [10]

For the given triangle, the value of x equals 30.9892 units.

Step-by-step explanation:

Step 1:

In the triangle, the angle is 40°, the opposite side has a length of 26 units, the adjacent side has a length of x units while the hypotenuse is not given.

To determine the value of x, we determine the value of the tan of the given triangle.

To calculate the tan of angle A we divide the opposite side's length by the the adjacent side's length.

tan A = \frac{oppositeside}{adjacent side}.

Step 2:

The length of the opposite side = 26 units.

The length of the adjacent side = x units.

tan A = \frac{oppositeside}{adjacent side}, tan 40 = 0.8390, tan A = \frac{26}{x} .

0.8390 = \frac{26}{x} , x = \frac{26}{0.8390} = 30.9892.

So x measures 30.9892 units.
