O.2 0.2 0.2 the answer is 0.2
yeah
Answer:
60 × 50 = 3000
7 × 50 = 350
60 × 4 = 240
7 × 4 = 28
3000 + 350 + 240 + 28 =3618
54 × 67 = 3618
Answer:
see explanation
Step-by-step explanation:
(1)
The sum of the 3 angles in a triangle = 180° , thus
a + b + c = 180
(2)
adjacent angles are supplementary, thus
b + d = 180
(3)
From (1) and (2)
b + d = a + b + c ( subtract b from both sides )
d = a + c
Answer:

Step-by-step explanation:
we have that


------> by supplementary angles
Substitute the values and solve for x




Find the value of angle R
Find the value of angle Q
