Answer:
The value of x° = 134°
Step-by-step explanation:
Given the angles of a quadrilateral
We know that the sum of interior angles in a quadrilateral is 360°.
so
100° + 51° + 75° + x° = 360°
226° + x° = 360°
subtracting 226° from both sides
226° + x° - 226° = 360° - 226°
x° = 134°
Therefore, the value of x° = 134°
VERIFICATION:
100° + 51° + 75° + 134° = 360°
360°= 360°
Answer:
d = 0.33
Step-by-step explanation:
First off, you want to get like terms next to each other. We'll move the numbers with variables on one side and normal numbers on the other. Since we're changing the sides of the equal sign they're on, this also changes whether their positive or negative.
d - d - 2d + 3d = 10 -7 + 8 - 10
Now that they're together, we can add or subtract them. The variables without numbers can be ones for this equation.
3d = 1
Now we divide 1 by 3 to find what d equals.
3d/3 = 1/3
d = 0.33
Answer: 268
Step-by-step explanation:
From the question, we are informed that 67 out of 206 species of birds found in the Badlands nest there and that 824 species were found in the Badlands. The number of those that nest there would be:
= 67 × 824/206
= 67 × 4
= 268
