Answer:
B
Step-by-step explanation:
the opposite angles of the quadrilateral ABDC are supplementary , that is
∠ BDC + 40° = 180° ( subtract 40° from both sides )
∠ BDC = 140°
Plug in -7 for x in the equation...
f(x) = 3 - 2( - 7 )
f(x) = 3 + 14
f(x) = 17
Answer:
x = 5
Step-by-step explanation:
im too tired to explain just trust me
(5) + 2 = 7
2(5) + 3 = 13
13 * 7 = 91
Answer:
This statement is false. Exterior angles are the angles created when the sides of the triangle are extended.
Step-by-step explanation:
Exterior angles are the angle between the any reference side and line extended from the adjacent side.
the sum of exterior and interior angle is 180 as it lies on a straight line.
_______________________________________________
based on above definition the given statement becomes false.
Hence, correct choice is option third
This statement is false. Exterior angles are the angles created when the sides of the triangle are extended.
Answer:
<u>x = 1.2√2</u>
Step-by-step explanation:
Taking the cosine value of the angle :
- cos 45° = 1.2/x
- 1/√2 = 1.2/x
- <u>x = 1.2√2</u>
