Answer:
85°
Step-by-step explanation:
So in geometry, the formula to find the <u>sum of all interior angles</u> is denoted as follows:
<em>n</em> = number of sides in the polygon
( <em>n</em> - 2 ) × 180° = sum of the interior angles
Using that formula, a triangle has 3 sides, so
<em>n</em> = 3 , therefore:
= ( 3 - 2 ) × 180°
= 1 × 180°
= 180°
Since the total sum of the interior angles of a triangle all have to add up to 180°, you can create the following equation and solve:
34° + 61° + <em>x</em> = 180°
Solve for x.
Answer:
$5.10
Step-by-step explanation:
We need to find 20% of 25.50
Multiply 20% * 25.50
Change to a decimal
.20 *25.50
5.10
Answer:
18
Step-by-step explanation:
v is 18 because 18+8 is 26 ♀️
Since congruence and similarity for polygons is posted in a specific order, we know that angle A=angle F, side A=side F, die B=side G, and so on. Therefore, we have that angle C=angle H = 9x-7=5x+13. Subtracting 5x from both sides to separate the x using the subtraction property of equality, we get 4x-7=13. Next, we can add 7 to both sides to get 4x=20, and divide both sides by 4 to isolate the x and get x=5. Plugging that into angle C or angle H, we get that 9x-7=9*5-7=45-7=38=5*5+13.
