Step 1 : find angle DFE
24 + 34 = 58
180 - 58 = 122
Step 2: angles in straight line add up to 180 so
180 - 122 = 58
Answer = 58
Answer:
16
Step-by-step explanation:
Input it in the calculator
Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6
Answer:
True
Step-by-step explanation:
- One way to find the least common multiple of two or more numbers is to first multiply each by 1, 2, 3, etc.
Reciprocal means invert it . for eg- the reciprocal of 1/2 is 2/1 and of 4/7 is7/4.
