Answer:
180
Step-by-step explanation:
Triangle: 1/2BH
Square: BH
1. Split up the shapes
2. Use the area formula for square and triangle
Square area: 135
Triangle area: 45
3. Add
Answer:
8
Step-by-step explanation:
because we know its an isosceles triangle angle A and C will both be the same and since we know A = 69 C will also be 69. we also know that angles in a triangle add to 180 so take away the two 69s from the 180 to get 42
then we work backwards if its 5x + 2 then we need to do 5x - 2 to get 40 then divide it by 5 to get your answer 8!
(sorry if the explanation doesnt make sense )
Answer:
$32,000
Step-by-step explanation:
overall cost for 4 years was $88,000. She made $44,000 after 4 years. After all 4 years she had to take out $12,000 to pay. 88,000-44,000=44,000 44,000-12,000=32,000
Answer:
Step-by-step explanation:
1. the 125g
b. 100ml for 1.79
By Cosine Rule:
CosT = (s² + r² - t²) /(2sr)
<span>CosT = (10² + 11² - 7²) /(2*11*10)
</span>
<span>CosT = 172 /220 </span>≈ 0.7818
T = Cos⁻¹(0.7818)
T ≈ 38.57°
T ≈ 38.6°
