Answer:
6) x = 36°, y = 18°
7) z = 7°
Step-by-step explanation:
6) 2x + 3x = 180°
5x = 180°
x = 36°
4y = 2x = 72°
y = 18°
7) 2z + 4 = 4z - 10
2z = 14
z = 7
Answer:
324 girls
Step-by-step explanation:
From the information given;
- Number of students = 864
- Staff members = 80
We are required to determine the number of girls in the school;
Total number of students is 864
Therefore;
Number of boys = 5/8(864)
= 540
Thus;
Number of girls = 864 - 540
= 324
Hence, there are 324 girls in the school
Answer:
Step-by-step explanation:
- <em>Assumed it is asking to find the value of x</em>
Given
- F is midpoint of DF
- DE = DF/2
- DE = 5x + 4
- DF = 78
Solution
- 5x + 4 = 78/2
- 5x + 4 = 39
- 5x = 35
- x = 7
Ok there are 11 animols all together because 1 rabbit + 6 elephants + 2 monkeys + 2 parrots
