Answer:
a) x = 260
b) g = 218
c) z = 30
d) h = 5
Step-by-step explanation:
a)
Predict a number; let's say x = 225
Too low; try with a higher number; let's say x = 270
Too high, we're closer.
x = 260
--------------------------------------------------------------------------------------
b)
let's say g = 230
Too high. Try g = 221
We're almost there. Let's try with g = 218
----------------------------------------------------------------------------------------
c)
Let's try with z = 15
Too low; try a higher number. z = 30
--------------------------------------------------------------------------------------------
d)
Let's try with h = 6
Too high; let's try with h = 5
Answer:
x = 18
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 5x + 72 = 180
6x + 72 = 180
6x = 180 - 72
6x = 108
x = 18
