Answer:
The triangles are congruent by HL
Step-by-step explanation:
The triangles are right triangles so we can use either HL ( hypotenuse leg) or LL (leg leg) if we know that two sides are congruent
We know one leg is equal to the other by the red line. The hypotenuse is the same since it is the same line.
The triangles are congruent by HL
Answer:
Situation: Water is liquid at 40°C above zero and it turns to ice at below zero temperatures. For example, water at 19°C below zero is frozen.
Step-by-step explanation:
The integer that represents 19°C below zero is -19.
The integer that represents 40°C above zero is 40.
The attached number line shows that 40 is at the right of -19. So -19 < 40.
The original price was 100% and the sale was -25%
100% - 25% = 75%
This means 75% = £33
75% = 3/4
If we divide the sale amount by 3 and them multiply by 4, we will get the original amount.
£33 / 3 = £11
£11 x 4 = £44
Answer:
39/89
Step-by-step explanation:
The sine of angle D would be opp/hyp from SOH CAH TOA. The opp side of angle D is 39, and the hypotenuse is 89 so the ratio would be 39/89
(5 x 5 + 67) / (0 + 56)
<span>(5 x 5 + 67) / 56 (The zero is irrelevant.)
</span><span>(25 + 67) / 56 (5x5 = 25)
</span>92/56 (25+67=92)
1.64 (92/56 rounded to 2 decimal places.)
Note that this answer assumes the format shown in the first line, specifically regarding the parenthesis. If there are some in a different format (say instead 5 x (5 + 67)) then the answer will be different.
