Fiona is not very smart so should know herself what frequency table she should use for her histogram
Answer:
(i)Here ∠HGB=∠AGE(vertically opposite angles)
∠HGB=110
∘
Now, for parallel lines l and m, with transversal t.
∠HGB+∠GHD=180
∘
(Angles on the same side of the transversal are supplementary)
110
∘
+∠GHD=180
∘
∠GHD=180
∘
−110
∘
=70
∘
(ii)For parallel lines l and m with transversal a
∠AIE=∠CJI (corresponding angles)
⇒x=100
∘
Answer:
15, 20, 25, 30
Step-by-step explanation:
If want to find the first multiple, we could actually use the equation: x + (x+5) + (x+5+5) + (x+5+5+5) = 90. After simplifying this term, we would get 4x+30 = 90 which then transforms into 4x=60 which simplifys to x = 15. Plug 15 into the original equation, and you would get the multiples 15 + 20 + 25 + 30 = 90.
Answer:
a)
Step-by-step explanation:
<u>Given: Step 3</u>
(JK)² = LK · MK and (LJ)² = LK · ML
<u>Step 4</u>
Addition property of equality
(JK)² + (LJ)² = LK · MK + LK · ML
<u>Step 5</u>
Distributive property
(JK)² + (LJ)² = LK (MK + ML)
