Starter activity

Observe the picture

The angle is decomposed into two smaller angles.

What is the measure of angle b?

b + 68o = 180o

b = 112o

Math bookpage 235

Learning Objectives

I can represent problems involving unknown angle measures using an equation.

Vocabulary

30o + 60o = 90o

Math book, page 236

a + 83o = 180o

a = 97o، 55o + 30o، = 85o، 90o + 55o، = 145o

u + 25o = 155o

u = 130o

m + 20o = 45o

m = 25o

p + 36o = 72o

p = 36o

m + 120o = 180o

m = 60o

k + 90o = 140o

k = 50o

x + 47o = 133o

x = 86o

a + 46o = 78o

a = 32o

a + 22o = 65o

a = 43o

Plenary

s + 90o = 127o

s = 37o

x + 70o + 70o = 180o

x + 140o = 180o

x = 40o

I need more help

I am getting there

I can do It!

Self Assessment! I understand!
