7 is the value of x, and 64° is the measure of the unknown angle.
Triangle angles of 76°, (9x+1)°, and 40° are provided.
According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180o, regardless of whether it is acute, obtuse, or right.
One of the most commonly applied properties in geometry is the triangle's angle sum property. Most often, the unknown angles are calculated using this attribute.
Now, the total of a triangle's three angles equals
76°+(9x+1)°+40°= 180°
⇒ 116+9x+1 = 180
⇒ 9x + 117 = 180
⇒ 9x = 63
⇒ x = 7
So, 9x+1=64°
As a result, x is equal to 7 and the unmeasured angle is 64°.

#SPJ1
Move all terms not containing y to the right side of the inequality
Inequality form:
y>10.3
Interval form:
(10.3,∞)
Answer: A: 63
Step-by-step explanation:
How i remember doing this, is that I put the numbers in ascending order (as in lowest to highest) and once I'm done i look for the middle number, so you have 22,44,63,63,71,80,92 it helps me by looking at the numbers on the right and left, or put them in groups, so we have 22,44,63 (that's one group) then we have 71,80,92 (that's another group) so the only number we have left is 63 the middle number, that's your answer :]
Answer:
The two angles mentioned are alternate interior angles, so they are congruent.
303 feet.
Step-by-step explanation:
If you draw off the flag you can see they are alternate interior and are congruent.
Also again, make a diagram it really helps a lot
:)
