Answer:
The slope is negative. The relationship is proportional
Step-by-step explanation:
Answer:
(49 - 29) + 1 =(50 - 29)
Step-by-step explanation:
The 20 comes from the subtraction of 29 in both sides of the previous step equality. In the following, I transcript the complete procedure and I add the step that you need to understand why 20 appears (in bold numbers):
29+20=49
49+1=50
(49 - 29) + 1 =(50 - 29)
20+1=21
50-29=21
hence, it was only nesseraty to subtract 29
You just multiply by 2 as you can see
4×2=8
8×2=16 and so on
64×2=128 therefore 128 is the answer
Time of the 20 to the x then get 420
Step-by-step explanation:
We know:
The sum of the measures of acute angles in a right triangle is equal 90°.
Therefore
(1) A + B = 90°
(2) 90° + B + C = 180° - angles on a straight line
(3) from (2) B + C = 90° → B = 90° - C
(4) from (1) and (3) A + (90° - C) = 90° → A - C = 0
Therefore
A = C → ∠A ≅ ∠C
