Answer:
The other angles of the isosceles triangle are 65° and 50°
Step-by-step explanation:
By definition, the base angles of an isosceles triangle are equal, therefore, we have;
Where one of the base angles = 65°, the other base angle = 65°
To find the third angle, we proceed as follows
Let the third angle = ∠3
Let the two base angles = ∠1, and ∠2 such that ∠1 = ∠2 = 65°
Where ∠1 = 65° is the known base angle
By the sum of the interior angles of a triangle theorem, we have;
∠3 + ∠1 + ∠2 = 180°
∴ ∠3 + 65 ° + 65° = 180°
∠3 = 180° - (65 ° + 65°) = 180° - 130° = 50° By angle subtraction postulate
∴ The third angle = ∠3 = 50°
The other angles of the isosceles triangle are ∠2 = 65° and ∠3 = 50°.
Pythagorean theorem =
Since you only have
and
you change the equation to
Giving you
= 135
Order of operations rules are important here: n/4-13
We must do the division first. Thus, n/4-13 translates to "the quotient of n and 4, less 13."
Answer:
There are no graphs, but the graph should look lyke this:
An open circle on the point "10"
And from the 10, the arrow should be going left, towards the negatives, or smaller numbers than the ten
Answer:
1st angle = 30
2nd angle = 60
3rd angle = 90
Step-by-step explanation:
- let ,1st angle be x , 2nd angle be 2x and 3rd angle be 3x
- x+2x +3x =180
- 6X =180
- x =180/6
- x =30
