Answer:
-5x = 20
x= - 4 ( if your question is finding the value of "x"
Answer:
28 squares
Step-by-step explanation:
column is 7 squares long, row is 4 squares long, 4x7 = 28 squares
Answer:
C
Step-by-step explanation:
∠ FHI and ∠ JHI form a straight angle and are supplementary, thus
3x + x = 180, that is
4x = 180 ( divide both sides by 4 )
x = 45
Thus
∠ FHI = 3x = 3 × 45 = 135° → C
3x-10+42+58=180 because angles in a triangle add up to 180
X=30
Z is equal to 3x-10
So z=80
80+42= 122
180-122= 58 (angle C)
Y = 122 because angles on a straight line add up to 180
